The document discusses radiation exposure during pregnancy from diagnostic and interventional radiology procedures. While thousands of pregnant women are exposed to radiation annually, for most patients the exposure is medically justified and the radiation risk is minimal. Higher doses from procedures like CT scans or radiotherapy administered during critical periods of pregnancy organ development can increase risks of fetal harm like malformations or mental impairment. The risks are dependent on the radiation dose and gestational period during exposure. Termination of pregnancy is generally not justified unless fetal doses exceed 100 mGy.
