Exposures can lead to absorption of radiation, either through external exposures or through internal exposures. Direct radiation is a common route of external exposures, since some types of radiation can pass through the skin and into the body. Inhalation is another common route of workplace exposures to radioactive particles, because radioactive dusts are often generated in cutting and machining operations. Short-term effects may include feeling nauseous or developing skin burns. Long-term effects may occur in almost any part of the body, but especially in the lung, bone marrow, and thyroid gland.
Radiation exposures can cause cancers in humans.
Other factors which affect whether or not you were harmed by your exposure include how much radiation you came into contact with, and for how long that contact lasted. There is no clear evidence of tests which can help catch early signs of the chronic diseases caused by radiation exposures. A doctor can advise you on what you can do to reduce your health risks, answer other questions you may have, and refer you for additional testing if needed.
