Why have there been decisions on termination of pregnancy after radiation exposure?
According to ICRP 84, termination of pregnancy at foetal doses of less than 100 mGy is not justified based upon radiation risk. At foetal doses between 100 and 500 mGy, the decision should be based upon the individual circumstances. The issue of pregnancy termination is undoubtedly managed differently around the world. It is complicated by individual ethical, moral, and religious beliefs as well as perhaps being subject to laws or regulations at a local or national level. This complicated issue involves much more than radiation protection considerations and require the provision of counseling for the patient and her partner. At foetal doses in excess of 500 mGy, there can be significant foetal damage, the magnitude and type of which is a function of dose and stage of pregnancy. For more information, consult ICRP 84.
