X-rays may cause miscarriage or abnormal fetal growth, but the amount of rays absorbed by a pregnant woman during a chest X-ray examination is very limited and may not cause abnormal fetal development. However, the amount of radiation that can be absorbed by a pregnant woman in one chest X-ray examination is very limited and may not cause abnormal fetal development. If, after the chest X-ray examination, the pregnant woman does not have a small amount of vaginal bleeding, abdominal pain and other abnormalities, and no fetal abnormality is found after the ultrasound examination, it is recommended that the pregnant woman should continue the pregnancy first, increase the number of maternity examinations appropriately, conduct regular maternity examinations, observe the fetal development at any time, and make sure that there are no chromosomal abnormalities in the middle of pregnancy. Once the fetal organ malformation, dysfunction, slow overall development and other conditions are found, it may be that the radiation has an effect on the fetus. If the fetus is stunted and difficult to cure later, it is recommended that the pregnant woman terminate the pregnancy as soon as possible to reduce the psychological and physical burden.
