| | NRC response to potassium iodide (Site not responding. Last check: 2007-10-25) |
 | | FDA guidance states that risks of side effects, such as allergic reactions, from the short-term use of relatively low doses of potassium iodide for thyroid blocking in a radiation emergency, are outweighed by the risks of radioiodine induced thyroid nodules or cancer, if the projected dose to the thyroid gland is 25 rems or greater. |
 | | If the licensee wants to implement a potassium iodide thyroid blocking program, the potassium iodide should be on hand (because it is not readily available), and guidelines should be developed to ensure rapid determination of whether a radioactive iodine spill or leak warrants administration of the potassium iodide. |
 | | It is important to stress that the use of potassium iodide is not a substitute for preventive measures; e.g., proper handling techniques, control measures, and emergency procedures that protect the individual from exposure to radioactive material. |
