Is the X-ray foreign object detection machine harmful to human body? This is a question that many people will have when using the X-ray foreign object detection machine. So will the X-ray foreign object detection machine really endanger the health? Today I will take you to understand.

X-ray foreign object detectors are the most commonly used at airports and stations. We understand that X-ray machines are currently the most effective security inspection tool, which can quickly distinguish prohibited items. Items that are strictly prohibited by ordinary passengers include fireworks, controlled knives, flammable or corrosive Sexual gases, liquids and toxic products, etc.

At present, the common safety gates and hand-held metal detectors on the market are to detect the eddy current generated in the metal conductor when the metal conductor is excited by the alternating electromagnetic field, and detect the eddy current to find the metal object; "Test paper" is to use the different drift speeds (expressed as "mobility") of different component molecules in the external electric field for component detection, especially good at distinguishing organic macromolecules such as drugs and explosives; The degree of polarization (indicated by "dielectric constant") under the action of an external electric field is different. To distinguish flammable liquids with low dielectric constants, most of the time a simpler "try to drink" method is chosen. Of course, none of this is X-ray radiation.

Among the many security inspection equipment, the earliest and most widely used X-ray inspection equipment is still the most widely used. Now let us answer a question, that is, whether the X-ray radiation of the security machine appearing in the security machine is harmful to the human body, and if so, how much damage will it cause to the human body?

Rumors about the radiation safety of X-ray foreign body detectors have been circulating on the Internet, and some people even worry that food will go bad after being irradiated. In fact, although the internal image of the object is obtained through the X-ray irradiation of the inspected object, the radiation of the security inspection machine is much smaller than that of the medical X-ray equipment. This is mainly because security screening equipment does not need to achieve medical diagnostic resolution, but only different imaging of different substances. According to the national standard GB15208.1-2005, the single inspection dose of X-ray security detector should not be greater than 5μGy/h (current radiation energy, absorbed dose unit), at the same time, at any position 5 cm away from the outer surface of the equipment (including equipment entrance and exit), the X-ray dose should be less than 5μGy/h, which is the same as the US FDA standard. In fact, the X-ray radiation dose of the security inspection machine is far lower than the national standard. Take a brand of X-ray security inspection equipment used by the Beijing subway as an example. The radiation dose at a centimeter is only one-tenth of the upper limit of the national standard. According to data reported by the United Nations Scientific Committee on the Effects of Atomic Radiation (STEM), the radiation dose of medical X-ray chest X-rays is 50 μGy. If you had to compare the two, drill into a screening machine 100 times to get the radiation dose you would receive on a chest x-ray. Of course, radiation doses are not simply superimposed, just like soaking in hot water at 40°C for one hour is not equal to soaking in hot water at 80°C for half an hour, and their effects on the human body are completely different.
