Bone marrow is one of the most radiation-sensitive organs as well as the cells lining the mucosa of the gastrointestinal tract and the brain.
Radiation is absorbed by tissues and cells of the body and can lead to the development of degenerative diseases like cancer when the exposure is less than 4 grams for an extended period but can be fatal in hours or days with a high exposure, greater than 6 grays, in a short time.
