Radiation sickness

Radiation sickness, malaise, nausea, loss of appetite, and vomiting occurring several hours after exposure to ionizing radiation in large doses. This occurs as an industrial or a war hazard or more commonly following radiation therapy for cancer, lymphoma, or leukemia. Large doses of radiation may cause bone marrow depression, or gastrointestinal disturbance. Skin erythema and ulceration, lung fibrosis, nephritis, and premature arteriosclerosis may follow radiation, and there is a risk of malignancy.
