Although the security check X-ray machine has a very large source of radiation, but the X-ray security machine has lead curtains on both sides of the block, the purpose is also to better avoid X-ray leakage, is relatively stable, so pregnant mothers do not have to worry too much. At this stage, there is no evidence to confirm that X-ray screening machines of mass equipment will have adverse effects on pregnant mothers. So far, there are no reports of negative effects of security checks on pregnant mothers and their babies in medicine. At the same time, the radiation source markers of the screening machines are in fact very low and the risk to the human body is close to zero. As a result, pregnant mothers are less likely to endanger their babies when they go through an x-ray screening machine.
Passenger security channel, including metal detector door and hand-held metal detector, most of these security inspection equipment is based on magnetic lines of detection, magnetic lines of detection can not pass through the metal material chemicals, if the traveler's body with a metal material items, the alarm will sound. There are some metal detectors or infrared sensor or laser, radiation source is smaller. Convinced that in our country in the airport subway and other public **** occasions to carry out the inspection of machinery and equipment, looking forward to the radiation intensity of machinery and equipment should be within the scope of the reliable. How much radiation intensity pregnant mothers need to bear when passing the security check to have an impact, at this stage there is no technical professional authority to carry out professional scientific research on these aspects, so it is not very good to draw random conclusions here.
Security machines undoubtedly have a source of radiation, but the damage is not so great. Security machines and medical X-ray machines are a basic principle, but its intake is lower than that of medical X-ray machines. Through the security check, is the case of bags and leather goods according to the x-ray security machine, x-rays are stored in the x-ray security machine inside, not easy to leak to the outside, not easy to our body damage. In any natural environment is a source of radiation, as long as the first trimester of pregnancy is not subjected to intense sources of radiation, the other do not care, not to mention the high speed train, in the process of everyone through the security process is a moment, there is no harm, all of them, can not worry.
The residual personal radiation dose brought on the object after the scanner and the rapidly passing group suffered electromagnetic radiation is even more worthless. That is to say, in the end, the light is not your own, and even if it is, you can not raise the risk of malformed fetuses.
