When a pregnant woman passes through a security gate occasionally, the tiny amount of radiation will not affect the growth and development of the pregnant woman herself or the fetus. However, if she passes through the security check gate frequently, it is possible that it may have some effect on the fetus. Usually, although there is a certain amount of radiation from security checkpoints, the amount of radiation is very weak. If a pregnant woman passes through a security gate once in a while, the tiny amount of radiation will not affect the growth and development of the pregnant woman herself and the fetus. However, if a pregnant woman passes through a security gate for a long time or frequently, the tiny amount of radiation many times may have some effect on the pregnant woman and the fetus. In daily life in addition to security gates, cell phones, computers, microwave ovens, etc. will also have a certain amount of radiation. Therefore, pregnant women should minimize the time of using electronic devices, reduce the number of microwave ovens, and should not pass through security gates too often. If the pregnant woman has abnormal symptoms, it is recommended to go to the hospital in time, under the guidance of the doctor to take appropriate methods to deal with.
