Are there any electromagnetic radiation in the recovery security door and the recovery X-ray security machine?

X-ray security inspection machines have been tested for radiation dose before leaving the factory, and experts from environmental protection departments and professional radiation inspection companies have been invited to test each security inspection machine, which fully meets the relevant national standards. The X-ray security machine used for subway security inspection has little radiation. Some special people, such as pregnant women, can stand by the machine or pass the security check, and the radiation dose is similar to that of mobile phones.

During the security check, the X-ray machine checks luggage, not people. According to China's "Basic Standards for Protection of Ionizing Radiation and Safety of Radiation Sources", a person standing at the entrance of the security inspection machine for about 10CM will reach this amount for 52 days, which is not enough to cause radiation damage to human body, including pregnant women who pass the security inspection machine. Will not affect the baby in the womb. Therefore, the majority of passengers can rest assured that they will be inspected when they pass the security check.

In fact, metal detectors and hand-held metal detectors meet the main safety standards and passenger safety standards. It obtains high resolution through digital signal processing by inducing parasitic current and uniform magnetic field, and the emitted magnetic field is very thin, which is harmless to electronic devices such as pacemaker wearers, pregnant women, the infirm and magnetic media.
