radiation protection

Prophylaxis against injury from ionizing radiation. The only effective preventive measures are shielding the source and the operator, handlers, and patients; maintaining appropriate distance from the source; and limiting the time and amount of exposure. In general, the use of drugs to protect against radiation is not practical because of their toxicity. An exception is the use of orally administered potassium iodide to protect the thyroid from radioactive iodine.
