After the door of the CT room is opened, if the CT is not in the scanning state at this time, there is no radiation. Because of the CT examination, only during the period of exposure scanning, there is radiation in the CT room. But when the examination is over and the exposure scan is stopped, there is no radiation in the examination room or outside the door. If you are pregnant or preparing for pregnancy, you should try to stay away from the CT room to avoid unnecessary radiation, after all, there are certain hazards of radiation. Because the early fetus is sensitive to radiation, it is easy to cause fetal malformations, so it is better to stay away from the CT room during pregnancy or pregnancy preparation. At present, everyone’s awareness of protection is also very strong, so you can better protect yourself.
