Is there radiation in the hand-held security device?

Hand-held security devices, like all electrical appliances, have certain radiation, but have little impact on human body.

Security instrument is our common security equipment. At present, the commonly used security instruments in public places include: magnetic metal detection plus manual inspection security instrument, high temperature alarm, metal detection door security instrument, X-ray security instrument and so on. In addition, with the development of science and technology, people are constantly developing new safety instruments with more functions.

In the traditional magnetic metal detector, when the detection coil is close to the metal object, eddy current will be generated in the metal conductor due to electromagnetic induction, which will increase the energy loss in the oscillation circuit, weaken the positive feedback, weaken the oscillation of the oscillator in the critical state, and even stop the oscillation because the minimum energy required for oscillation cannot be maintained. If this change can be detected and converted into a sound signal, it can be judged whether there is a metal object under the detection coil according to the presence or absence of sound. However, this kind of security instrument is usually slow and the workload of security personnel is also very large.

The built-in antenna of the new intelligent security inspection instrument can capture the millimeter wave reflected from the human skin surface, and the radiation amount of a security inspection is only one thousandth of that of a mobile phone signal. Candidates just need to stand still and raise their hands. The security door can read all the information outside the skin of the subject within 2 seconds, and generate a 360-degree detection map with millimeter resolution, which can "see at a glance" non-metallic dangerous goods and contraband that cannot be detected by traditional security equipment, such as corrosive substances, flammable and explosive liquids and gels. In addition, it also has super learning ability, and can learn endless contraband. Just upgrade the software to meet the constantly updated security requirements.
