Security gates, also known as metal detector doors. This is the gate metal detector. It is mainly used to detect whether a person's body carries metal objects. With the development of society and the diversification of demand, the application of security gates has become more and more extensive. However, according to the contact between the technicians of the pastoral and the security gate users, many customers have realized the use of security gates. Misunderstanding: 1. The user believes that the security door can detect all prohibited items, including dangerous substances in liquid, powder and other conditions. 2. The user thinks that the security door can only give an alarm prompt for the controlled tool, but can completely exclude other metal or electronic items such as belt buckles and mobile phones. 3. The user thinks that the security door can be installed normally in any environment without any influence. 4. The user also believes that the security door can display the exact location of the human body through the image after detecting the prohibited item. In response to the above customer's understanding, the pastoral security inspection is here to explain with you one by one, so as not to cause unnecessary misunderstanding in the later period: 1. The current general security gates in the market refer to metal detector security gates (except for the latest millimeter wave human body security devices and terahertz human body security devices). That is to say, only articles containing a certain amount of metal can be detected, and articles without any metal components can not be detected. 2. Up to now, metal detection security doors, including imported security doors, have the ability to adjust the sensitivity of detection, and can also detect mobile phones and controlled tools without excluding some zippers, buttons, and small keychains. However, the principle of this exclusion is obtained by reducing the sensitivity of the security door detection, rather than the intelligent identification technology, so the security door cannot detect smaller metal objects without excluding large metal objects. 3. The metal security door adopts the weak magnetic field induction technology, so it has certain sensing ability for metal objects, magnetic items and strong wireless signals. These factors will have certain influence on the normal operation of the security door. . Therefore, the installation environment of the security gate needs to avoid the existence of these factors. 4. The current security door can emit sound and light prompts after detecting the metal objects carried by the person's body. It can also indicate the height of the human body where the metal is located through the segmented LEDs on the left and right sides of the security door. The photo accurately displays the exact location of the human body. 5. There is also a very important problem. The use of security gates must be carried out in accordance with strict security procedures to achieve maximum effect. For example, personnel should first carry their mobile phones, coins, key chains, etc. with metal or electronic objects before passing through the security gate. Take it out and put it aside and pass the security door. Avoid the interference caused by other metal objects, but many units and places in reality can't do this. The personnel are directly in and out, even with a backpack, so that the meaning of security is lost. Any single precautionary measure is imperfect, and only the physical defense + civil air defense + technical defense can achieve the best security inspection results.

A terrorist attack on the Russian subway was initially suspected to be a loophole in the subway security system. On the afternoon of April 3, in Russia, a subway from St. Petersburg's [Hay Square Station" to [Technology College-1 Station" exploded, and the explosion was located in the third carriage of the subway. The explosion was caused by a small homemade device with an explosion equivalent of about 200-300 grams of TNT, including destructive items such as steel nails. After the explosion, various government departments in Russia responded quickly and rescuers arrived at the scene five minutes after the incident. Local time 15:00: The Russian National Counter-Terrorism Committee stated that a kilogram of shougongzhadan disguised as a fire extinguisher was discovered and destroyed at the St. Petersburg Uprising Square subway station. Local time 15:40: All subway stations are closed. Local time 15:53: The subway station evacuation work is all over. Russian President Vladimir Putin is preparing to hold talks with Belarus`s overall Lukashenko at the time of the explosion. He quickly responded that the relevant authorities have launched a comprehensive investigation on the matter. Two hours after the incident, the Russian Attorney General`s Office declared the St. Petersburg subway bombing as a terrorist attack. At present, the cause of the incident is still under investigation. According to the Russian "Rambler" news network, Sergei Goncharov, president of the Russian "Alpha" anti-terrorist army veteran association, said in a live broadcast of "Russian 24" that Russian President Vladimir Putin is inspecting in St. Petersburg during the St. Petersburg subway terrorist attack. This is no coincidence. On the day of the explosion, Russian President Vladimir Putin met with Belarusian President Alexander Lukashenko in St. Petersburg and participated in the [Truth and Justice" media forum. So how did the terrorists bring the bomb into the subway? Investigations by relevant departments found that the security system problem of the St. Petersburg Metro had already existed very early: before 2016, all the subway stations were only guarded by the police and did not have any security facilities. In 2013, the St. Petersburg Metro Company announced that it will invest 5.9 billion rubles to renovate security equipment and monitoring systems for all subway stations. It is planned that by 2015 all passengers must pass through security gates, security inspection machines and metal detectors to enter the subway station. The installation of safety equipment systems and training staff in the halls of 73 subway stations have cost more than 2 billion rubles in the past two years. The main equipment supplier is Moscow CHT, which is also responsible for the security system setup of the Moscow Metro. The head of the company, Dmitry Bassaf, insists that the security equipment they provide is safe and reliable. He does not know how the terrorists brought the bombs into the subway station. He said that this may be caused by human factors. According to the working guidelines, there should be 5 staff members in each subway station hall to cooperate with the safety inspection, but often there are only 1-2 staff members in the hall. When many people enter the hall at the same time, the security inspection work cannot be carried out. . According to RIA Novosti, it is possible for terrorists to verify the security system in St. Petersburg several times before. In March of this year, the emergency department closed the subway station at least five times due to the discovery of unknown objects. Just on April 3, six hours before the tragedy, a similar situation occurred at the Heihe Station. The subway station was closed for nearly an hour. Shortly before the explosion, the "Uprising Square" station was also closed due to the discovery of unknown objects. In the future, it is necessary to further improve the construction of security inspection equipment and systems to prevent such incidents from happening!

In order to ensure the safety of the masses of the people, the security and security work and methods of various places are also emerging. According to the Shenzhen News Network: Recently, a new type of human body security instrument has been added to the Futian Station of Shenzhen Metro, which has aroused public concern. When taking the subway from Futian Station, in addition to the routine routines such as baggage check-in security, the passengers will be told by the security inspector that they need to pass through the human body security scanner before they can pass. The reporter experienced the whole process and found that the entire scanning process took about time. 2 seconds or so. Many people at the scene told the reporter that the efficiency of the human body security device is very low, and it is really not a big deal to put only one device at present. The reporter saw the human body security instrument that triggered the public's hot discussion at the entrance and exit of No. 31 Futian subway station. It is understood that this security device is called the TAI-30 millimeter wave human body security instrument. It was posted by the Shenzhen Public Security Bureau Bus Branch a week ago. The pilot project of Futian Metro Station was the first in the city. The purpose is to further enhance the public safety of the Shenzhen Metro area and prevent prohibited items such as inflammables and explosives from entering the subway. At the same time, the pilot is mainly to explore the security inspection mode that can improve the security check speed of subway stations through high-tech trials. According to the on-site staff, the human body security instrument has been in operation for a week. The people in the queue at the peak period will be longer than other security ports. Some passengers will choose other security ports. According to the staff, the millimeter wave personal security instrument used in the pilot has a center frequency of 35 GHz and is harmless to the human body. According to the data, the radiation measurement of the device is one-thousandth of that of the daily use of mobile phones, and the radiation power reporter randomly interviewed several passengers in the station hall. A famous lady passenger believes that the security check method in Shenzhen relied on the security check machine at the entrance of the subway. There are some loopholes in the way that no baggage person enters directly. It is a good evidence that a pet was artificially brought to the subway. This is a good reform measure that can completely prevent passengers from carrying prohibited items into the subway to ensure passenger safety. However, the use and safety of the human body security device should be informed to the public in advance to avoid unnecessary misunderstandings. Another passenger believes that the choice of piloting a human security instrument at Futian Station is debatable, because the subway as the most transported public transport, the primary consideration should be transport efficiency. Futian Station is located in the core business district of Shenzhen. The passenger traffic is huge. The launch of the human security instrument is tantamount to increasing the passenger's commute time and adding unnecessary trouble to passengers. The practice of placing only one human body security device at the entrance and exit of the three gates is obviously unscientific and too formalistic. The subway said it will continue to follow up on the follow-up work!

Since its discovery, X-rays have been used in medical clinics for their unique penetrability, photosensitivity, ionization and biological effects. Medical diagnostic X-ray examination is an indispensable medical imaging examination in clinical medical technology because of its high diagnostic value, but it can cause harm to the human body if it is used improperly. Pay attention to the following points during use: 1. The X-ray machine and medical X-ray equipment users of security inspection must learn the X-ray professional technology of the system, be familiar with the structural principle, performance and specification characteristics of the machine, master its operating procedures and safety protection rules, and strictly follow the formal operating procedures. . Instrument safety: Before each shutdown and power-on, adjust the instrument pointers such as the gauge and power meter to the lowest position, and then adjust to the normal condition when using it, so as to avoid the instrument suddenly disconnecting power and smashing the pointer. 2. Strictly control the use conditions: firstly, the power supply voltage should be calibrated after starting the power; the filament voltage should not be too high, and the voltage of the filament directly affects the volatilization degree of the X-ray tube filament. Therefore, it must be used correctly according to the regulations, and the machine should be shut down in time after the machine is stopped. In order to avoid the reactive power consumption of the filament. 3. Remember to prohibit over-capacity. Use X-ray machine for super-kV. When using X-ray machine, be careful not to overload the machine. Generally, under the premise of meeting the diagnostic needs, try not to exceed 80% of the rated X-ray tube capacity. . For X-ray machines with long service life, the conditions should be reduced as much as possible. 4. When the machine is in continuous use, pay attention to the intermittent time of the machine. Note that the external temperature of the X-ray tube generally does not exceed 50 °C. It is strictly forbidden to adjust each adjustment knob or suddenly shut down when the machine generates radiation. The machine parts should be in a safe state at the end of the work. 5. When the machine is in use, abnormal sound, odor and pointer indication abnormality should be shut down in time, cut off the power supply, and respond to the maintenance personnel. It is strictly forbidden to work with the disease to avoid the malfunction. 6. The security X-ray machine should pay attention to the strict implementation of the switch machine rules during the use process. After the power is turned off, the guest must be powered off after the power light is turned off. The environment must be kept dry and ventilated.

The security X-ray machine is one of the X-ray machines and refers to the X-ray machine used for security inspection in public places. It can be seen at airports, public inspection units and other places. It has a strong practicality and can check almost any item. The security X-ray machine is an electronic device that performs inspection by means of a conveyor belt to carry the inspected baggage into an X-ray inspection channel. The baggage enters the X-ray inspection channel, which blocks the package detection sensor, and the detection signal is sent to the system control section to generate an X-ray trigger signal that triggers the X-ray source to emit the X-ray beam. A bundle of X-ray beams passing through the collimator passes through the object to be inspected on the conveyor belt, the X-rays are absorbed by the object to be inspected, and finally the dual-energy semiconductor detector mounted in the channel is bombarded. The detector converts the X-rays into signals, which are amplified and sent to the signal processing chassis for further processing. X-ray is an electromagnetic wave that can penetrate opaque objects such as metal, ceramic, glass, wood, cardboard, and leather. The Makino intelligent security X-ray machine can display images of different colors on the display according to the degree of X-ray absorption of the object. Simply put, orange represents organic matter, such as food, plastic, etc.; books, ceramics, etc. are shown in green; metals are shown in blue. At this time, the security inspector can quickly check the perspective image of the X-ray scan, and can rely on rich experience to judge whether there is a contraband. With the development of technology and continuous improvement, the current security X-ray machine also has the function of identifying, analyzing and alarming specific items. It will play an increasingly important role in the security field.

X-ray security inspection machine - is a classification of X-ray security inspection equipment, also widely known as X-ray machine, X-ray scanner, security inspection machine, security X-ray machine, security instrument and so on. That is to say, the X-ray penetrating imaging principle is adopted, and the baggage parcel is inspected in the form of an image after being collected and processed. The Mama Security X-ray adds a number of accessibility features to traditional technologies: 1. Automatic sensing function: After the X-ray machine is turned on, it automatically enters the standby state. At this time, the belt is static by default. When a person puts the baggage package on the conveyor belt, the security check-up machine automatically starts the operation through weight sensing or infrared sensing. Detection, within 0-1 hours (can set the time freely), if no other baggage is placed, the conveyor will automatically stop running. It is convenient and energy efficient. Of course, this is an essential additional feature. 2, automatic identification of items: This is a very practical function, the Makino security inspection machine has the ability to detect, identify, prompt, and standard items. The animal husbandry security inspection machine can identify and alarm the tools, weapons, gasoline, ethanol, toluene, sulfuric acid and other items, greatly improving the security inspection efficiency and reducing the work intensity and effectiveness of the security personnel. 3. Consistent identification of the identity of the person and the person: Through the consistency record of the identity of the person and the articles carried, the effectiveness of the relationship between the person and the object and the retrospective effect are effectively increased, and the pre-criminal personnel can be alerted in advance. . 4. Remote monitoring and management: The Makino X-ray machine can manage and view the security inspection site from a long distance through the Internet or LAN. In case the incident occurred on the site, the local security system will be damaged. It can also be operated through the remote management system. Data saving and recall. Effectively increase the security of security. There are more additional functions of the Makino X-ray security inspection machine. Later, interested friends can also consult by phone. For everyone's safety and harmony, please understand the security products and understand the security inspection work!

In today's society, people are particularly important for food safety. The name is food, and safe food is more acceptable. To check whether the food is safe, the food metal detection equipment is used. This is a special inspection instrument for food. It can detect a variety of items and has been highly valued and widely used by the food industry. Why would you use it? To know that nothing can't be established in the market without any skill, now we can simply look at the "four major specialties" of food metal detection equipment, which is also an advantage. Food metal detection equipment advantages: 1. Hygienic design, easy to clean; 2. It can avoid product accumulation, blockage and cause mold; 3. Quick release lock can ensure quick installation and disassembly of the reject device; 4. Equipment cleaning is quick and easy.

Special transmission mechanism design Zui Dacheng metal detection sensitivity, modular design can be flexibly customized according to different requirements, mirror stainless steel, open transmission system, easy to clean. Over the years, the company has continuously innovated and developed through continuous efforts and the introduction of technology that absorbs the Japanese Yudao needle detector. Now it has strong technical strength and development capabilities to make the products constantly updated.

Security gates from a wide range of fields, in addition to general manufacturing companies, such as electronics, wire and cable, electrical appliances, gold and silver jewelry, precious metals and other processing industries, can also be used in government departments, such as police, courts, procuratorates can also be applied to Public places such as stadiums, exhibition halls, museums, etc. The third is for temporary metal security doors. Safety gates can also be applied to the need for scientific prevention. Use requires attention. Through the security gate, the magnetic field in the area can reduce the entry of workers and metal objects, ensuring accurate, objective and complete, without human intervention. 2, security door using common sense metal detection security door, size 2220 mm (h) X820mm (w) X522mm (d), channel size 2000 mm (height) X700mm (w) X522mm (d), although the size is not strictly regulated However, based on the standard size, the error cannot be greater than 50 mm, and more custom non-standard sizes. Note that if you want to use it, in addition to the full rainproof security door, the security door is generally not rainy, and the outdoor activities must be added to the non-waterproof security door. At the same time, within 1 meter of the safety door, there must be no large metal objects, so as a large steel door, elevator, iron, and not near the object to generate a magnetic field, such as distribution boxes or electrical equipment. Security objects pass through the security gate, when you want to traverse, queue, but should not touch the door. 3, security door to buy a security door to buy must pay attention to the product has a high level of security features. The magnetic field distribution should be uniform, 100%, to distinguish smaller metal objects from the consistency of individuals carrying various metal objects. In addition, the security door must have good immunity, whether it is motor type noise and small metal moving vibration noise, can be immune. Of course, in addition to these two points, the safety is good, but it also requires the use of safety and environmental protection, and the operation is simple, convenient, functional, and practical. 4, how to identify high quality security door quality and safety doors, safety, stability is also crucial. It can also play a role in safety because an unstable safety door is likely to cause an alarm or a leak alarm. Therefore, in the purchase of the security door, the brand that found its own technical strength, at the same time handle the stability of the security door, has a high resistance to interference. Second, high quality security doors can be accessed from the same metal specimen. Smaller volume metal samples and the same omissions make the door safe.

Two explosions in Pakistan in one day killed 132 people An explosion in Pakistan's Balochistan province killed 128 people On the 13th, a campaign of suicide bombings in a campaign in the Mersdon region of Balochistan province in southwestern Pakistan. According to local media reports, the attack has killed at least 128 people and injured about 150 others. The extremist organization claimed to have created the attack. According to local media reports, in the afternoon, the Balochist People`s Party held an election rally in the local area. When a team leader of the party arrived at the rally, a suicide bomber detonated the explosives carried on him, causing a large number of casualties. Local police said more than 1,000 people were present at the time of the incident. After the attack, security personnel and rescue workers launched an emergency response and sent the injured to a local hospital. Quetta City Hospital, the capital of Balochistan Province, announced its entry into a [state of emergency". Pakistani President Hussein and Transitional Prime Minister Al-Mulq condemned the attack on the same day and demanded that the entire party rescue the injured. At present, extremist organizations have claimed responsibility for the attack. Balochistan is located in southwestern Pakistan. Al Qaeda and the Pakistani Taliban have long been entrenched in the mountainous areas of the province. In addition, extremist organizations have begun to infiltrate into the region in recent years, and terrorist attacks have occurred in the local area. Bomb attack in Khyber Pakhtunkhwa Also on the 13th, a bomb attack on political party leaders occurred in the Khyber Pakhtunkh province of northwestern Pakistan, killing at least four people and injuring 39 others. According to local media reports, the attacker detonated a bomb that was previously installed on a motorcycle. Pakistan`s recent attacks on elections Pakistan will hold a National Assembly election on the 25th of this month to produce a new ruling party or ruling coalition in Pakistan, and on this basis, a new government will be formed. Since the beginning of this month, Pakistan has entered a critical stage before the election. There have been many terrorist attacks against election parties in various places, causing many deaths and injuries. On the 10th, a Pakistani People`s National Party was suicide bombing in a campaign rally in Peshawar, the capital of Khyber Pakhtunkhwa, killing 22 people including the party`s leader, Halon Bilol.

Select the same metal sample to detect the gate, the smaller the better. Traditional safety doors should be able to detect all metals (except for specially designed detectors), and all metals can be tested in strict accordance with the [sensitivity" standard of the gb15210 - 2003 national standard. The metal samples we choose are best included in the national standard. Metal signal detection capability is the hallmark of the metal detector manufacturer's technical strength. Manufacturers of non-ferrous metals and ferrous metals are able to perform the same detection, stability and good conditions to detect small metals, and the sensitivity control is clear. If the quality of the poor quality is slightly higher, when the sensitivity is high, nothing can cause an alarm, the sensitivity will be lower, and the metal can be used to alarm. This kind of safety door is due to poor internal circuit design, and the control is not linear and cannot be used. In addition, due to the direction of the electromagnetic waves, the metal detection is oriented, and in order to reduce the electromagnetic wave signal corresponding to the most powerful surface, the minimum surface-cut electromagnetic wave signal is correspondingly weakened. A good manufacturing company can handle the directionality of the magnetic field. Therefore, the effect of detecting a metal object in the same detection area is not different. If the difference is larger and the omission is greater, then the user should choose a product with good direction detection. The same metal object is selected by the tester to pass through the various locations of the security door, and the metal objects are passed in different directions in each location, and the products with less false negatives are selected. For the elimination of small metals, it is necessary to adjust the sensitivity to a suitable position when detecting a large metal. The test method is the same as above.

How large is the security equipment, security inspection equipment, baggage security inspection machine, security inspection machine, X-ray machine Is the radiation from the security equipment of the subway, railway station and airport "shooting people"? We must make clear: ● The security door that the personnel pass is a metal detector, not an X-ray device. The inspection of the item is to use X-ray. ● From the data point of view, the standard radiation leakage dose of the security inspection machine is close to the radiation background value of the natural environment, and there is no risk of radiation from the side. Recently, the media reported that there may be a radiation leak in the Shenzhen Metro security inspection machine. Since then, some inspection machines of the Shenzhen Metro have been suspended. The Provincial Environmental Protection Agency has also issued a document requesting environmental protection law enforcement inspections for radiation installations throughout the province. The aftermath of the incident has not been broken. Many people still worry that they have been exposed to security screening machines. Have they been exposed to nuclear radiation? Pregnant women are even more worried. Will the security screening machine harm the intra-abdominal baby? Director of Nuclear Medicine, Sun Yat-sen Memorial Hospital, Sun Yat-Sen University, China Professor Jiang Ningyi, vice president of the Nuclear Medicine Branch of the Physician Association, said that [radiation" is daunting. In fact, radiation is everywhere, and it is closely related to people's lives. [It can be said that human evolution is accompanied by radiation." 80% of radiation comes from nature Professor Jiang Ningyi said that "radiation" includes natural radiation and artificial radiation. 80% of the radiation received by the human body comes from nature, including cosmic rays in outer space, helium, and radioactive radiation naturally present in ordinary substances in nature. The soil, air, houses, oceans, rivers, food, vegetables, drinking water, etc. around us contain trace amounts of radionuclides. The remaining 20% of people are radiation, the most important of which is medical radiation. Radiology, nuclear medicine, and radiotherapy in hospitals use "radiation" to diagnose and treat diseases. In addition, the industry also has industrial flaw detection using the principle of [radiation", radiation breeding in agriculture, radiation disinfection of daily necessities, nuclear power plants, etc., all of which are pioneering efforts to improve the quality of life by using radiation. In short, as long as the reasonable use of radiation is safe, it can benefit humanity. "Radiation" does harm health as well, but the prerequisite is excessive exposure. Security radiation is much lower than medical X equipment The security equipment of subways, railway stations and airports is a kind of equipment for detecting objects. There are many types, the most common one is channel type X-ray machine. When the object passes through the security inspection machine, the X image is obtained, and the image is processed by the computer and displayed on the computer screen, and the image can be recognized to evaluate the security of the object. Professor Jiang Ningyi said, [It is like a hospital X-ray examination, but the X dose of medical X equipment is much higher than that of the security inspection machine. The tube current of the medical chest-piercing machine is 50 times that of the security inspection machine." The studio in the security inspection machine must have a certain dose of X-rays, but only the luggage items are put in and checked, the human body will not enter, and thus will not touch the rays. According to media reports, recently, Li Qing, director of the Guangdong Provincial Environmental Protection Department, also responded to online interviews on the provincial government portal. Security inspections in public places such as airports, railway stations, and subways were conducted separately for personnel and articles. Security gates passed by personnel. It is a metal detector, not an X-ray device. The inspection of the item uses X-rays, so the person is not exposed to X-rays through the security check. Then, will people be exposed to radiation from the X-ray device that detects the object? Professor Jiang Ningyi believes that, in general, an inspected security inspection machine will not have this possibility and should be safe. . From the data point of view, the standard ray leakage dose of the security inspection machine is close to the background value of natural radioactivity. According to media reports, Li Qing, director of the Guangdong Provincial Environmental Protection Department, also said during the interview on the website that according to the relevant UN technical report, staying in the vicinity of the X-ray security inspection machine for 5 hours is equivalent to a medical X-ray chest, so it will not It affects the health of the surrounding population. Medical X inspection is beneficial and harmless Then, since the X dose of medical X equipment is much higher than that of the security inspection machine, is there any danger of [shooting" for medical examination? Professor Jiang Ningyi said that whether radiation has an effect on the human body depends on the amount of radiation received and radiation. The total amount, the time of exposure, and the body's ability to regulate these radiations. There is a basic principle of use for medical radiation: the justification, optimization and dose limitation of exposure radiation. That is, the patient needs to take the irradiation inspection and treatment for the needs of the treatment. The radiotherapy is the most superior technology and equipment. The hospital radiologists are all [radiation" professionals, ensuring that the patient is within a certain limited safety range. A small amount of radiation is accepted, so patients do not need to have this psychological burden at all.

Security door manufacturer: Is the security door harmful to the human body? The security door is a detection device for detecting the presence or absence of metal objects, also known as a metal detector door. As the name implies, the function of the security gate is to check whether the person passing the security gate carries metal objects. The working principle is simply to form a magnetic field transformation to cause electromagnetic induction of metal objects, thereby discovering metal objects. Some high-grade security doors can further sense the shape of metal objects to determine whether they are dangerous objects such as knives. In summary, the security gate is passively inspected by a magnetic field, rather than the traditional sense of illumination. To make an inappropriate metaphor, we can regard the security gate as a super simplified version of the nuclear magnetic machine. Having said that, I think everyone has already understood that the security door has put an end to the so-called radiation hazard in principle. Through the security door, even passing the security door many times in a day will not cause harm to the body. The security door manufacturers are here, and we will popularize the radiation that people often mention. Radiation is divided into ionizing radiation and non-ionizing radiation. The former is high in energy and can cause rotation and power phenomena of atoms or molecules, such as nuclear radiation and X-ray radiation, which we must protect. The radiation sources encountered in our daily life, such as WIFI, mobile phones and sunlight, are non-ionizing radiation. Such radiation does not change the traits of the objects in principle, but the harmful effects of large doses of such radiation are still underway. Therefore, countries around the world still have corresponding restrictions on the generation of such radiation. China's safety standards are below 40 microwatts per square centimeter (μW/cm2), which is safe. In daily life, the radiation we are exposed to, such as the mainstream wireless router radiation is 24-31 (μW / cm2), while the mainstream mobile phone standby time is 17-25 μW / cm2, the call surged to 93 μW / cm2. What we need to point out is that the distance of non-ionizing radiation is extremely high. The WIFI signal of the wireless router propagates 1 meter in the air, the radiation level will drop to 4.5-6.8 μW/cm2, and it will drop to 0.8μW/cm2 after 2 meters. , far below the national standard.

The correct use of handheld metal detectors is as follows: 1. Turn on the power switch and hear a [beep" sound, indicating that the power is on and the green light is on. If the green light does not light, it means that the battery is not installed or the battery is not in good contact. If the sound continues to vibrate continuously or continuously, it means the battery can no longer be used. It should be replaced with a new one. 2, sound, vibration transfer switch selection: press the red button switch, the alarm mode is vibration. Release the red button switch and the alarm mode is sound. 3. After turning on the power, you can perform high-sensitivity detection. The wing technology reminds you that the hand grip handle sweeps the detection surface around the object to be tested. When there is metal object, it will sound an alarm or vibrate. At the same time, the green light turns red. Light; stop sweeping, alarm sound or vibration stops, red light turns green. 4. Low sensitivity test: If you need to eliminate objects with small volume in the metal, you can press and hold the low sensitivity switch. When the metal object is swept around, the alarm sound or vibration is emitted. At the same time, the green light turns into a red light; when the sweep is stopped, the sound or vibration stops, and the red light turns into a green light. Because the sensitivity is reduced by more than 5 times. Therefore, the measured metal is generally a relatively large metal. 5. Sanjibao Technology reminds you that sensitivity adjustment should be made if the detection distance does not meet the specified requirements or the sensitivity is too high to cause instability or sound or vibration when there is no metal detection in the human body. 6. Put the sound and vibration switch in the "release" state, use a small flat-blade screwdriver to extend from the small hole in the detector handle to rotate clockwise, adjust to the sound, then turn counterclockwise until it just sounds. Then rotate a half turn counterclockwise until the sensitivity meets the requirements.
