The allowed exposures from specific radioactive sources to the public are limited to 100 mrem. Medical X-rays generally deliver less than 10 mrem.
All kinds of ionizing radiations produce health effects. The damages incurred by different kinds of tissue vary with the type of radiation to which the person is exposed and the means of exposure. Direct exposure to radiation and radiation emitters (radionuclides) can affect the whole body while inhalation or ingestion affects tissues inside the body. The body attempts to repair the damage caused by the radiation. However, at times the damage is so severe and widespread that repair is impossible. Radiations can damage the process of normal cell division leading to cancers. Non-ionizing radiations do not affect at molecular levels. They may cause electrical shocks and burns. Prolonged exposure to microwaves radiation, which is non-ionizing, may cause cataracts.
The thyroid gland is one of the most radiation-sensitive parts of the body, especially in babies and children. Most nuclear accidents release radioactive iodine into the atmosphere. This is absorbed by the body. Absorption of too much radioactive iodine can cause thyroid cancer to develop several years after exposure.
