Iodine Prophylaxis and Nuclear Accidents

Due to high volatility and therefore extreme potential environmental mobility, in acute phases of a nuclear accident radioactive isotopes of iodine pose serious risk. The critical organ for iodine is a thyroid. A number of studies dealing with thyroid protection from exposure to radioiodine have shown that radioiodine uptake by thyroid can be effectively blocked by administration of stable iodine, usually in the form of potassium iodine pills. However, this protective action requires precise timing, otherwise is counterproductive. International Atomic Energy Agency recommends potassium iodide prophylaxis in cases when an avertable thyroid dose by protective action exceeds 100 mGy. In this paper is given review of the experiences and practices on potassium iodide on thyroid protection. These informations are necessary in discussion and decision making process on KI prophylactic programmes in nuclear emergency situations in Croatia. If Croatia adopts such programme, it still remains to develop the most effective way of KI stockpiling and distribution or predistribution.
