Pregnant women can go through the security gate, security devices, although some of the radiation, but the amount of radiation is relatively small, will not have an adverse effect on pregnant women and the fetus. But everyone’s physical condition is different, some physical weaker pregnant women, even if the exposure to a very small amount of radiation does not rule out a certain impact on the fetus, for safety reasons, it is recommended that pregnant women go out if you need to go through the security gate, you can apply to the staff to manually check the security check, which can be exempted from the use of detectors to detect, but also to avoid pregnant women come into contact with the rays. Because pregnant women during pregnancy is best not to contact any radiation device, especially in the early stages of pregnancy, is the formation of fetal organs and development of the critical period, if the exposure to radiation is very easy to cause fetal deformities and other conditions, although the detection of the detection device at the security gate of radiation is small, but can not be exposed to contact or as far as possible not to contact.
