Radiation sickness
Radiation sickness occurs from exposure to a large amount of radiation. The exposure may be in a series of doses spread over time (chronic) or in a single large dose (acute). Radiation exposure may be accidental or intentional. The two main types of radiation are penetrating (ionizing) and nonpenetrating (nonionizing). Penetrating radiation affects you by entering your body and depositing radioactive energy into your tissues, which then can cause cell damage or cell death. Nonpenetrating radiation doesn't pass through your skin. A large dose of penetrating radiation may kill bone marrow cells, while a large dose of nonpenetrating radiation may burn your skin. Radiation is a cancer-causing agent (carcinogen). Exposure to radiation can increase your risk of cancer. Large doses of radiation can cause other adverse health effects, including cataracts and mental retardation in the children of mothers exposed during pregnancy. Treatment for radiation exposure is designed to relieve signs and symptoms. Signs and symptoms The signs and symptoms of radiation sickness may include:
The signs and symptoms of radiation sickness and their severity depend on how much radiation you receive and the tissues that are exposed. The way you receive radiation — by breathing radioactive material, by ingesting it with food or water, or by being exposed to rays of radioactive particles — also has an effect on the signs and symptoms of radiation sickness.
