Radiation illness is the result of a substantial dosage of radiation being given to your body over a short time (acute). The absorbed dose, or the amount of radiation taken into the body, influences how unwell you will become.
Radiation poisoning or acute radiation syndrome are other names for radiation illness. Common imaging techniques that employ low-dose radiation, such as X-rays and CT scans, do not induce radiation sickness.
Moreover, radiation illness is dangerous and often lethal, but it is uncommon. Most cases have taken place after nuclear industrial occurrences, such as the 1986 explosion and fire that affected the nuclear power plant at Chornobyl, Ukraine, since the atomic bombings of Hiroshima and Nagasaki, Japan, during World War II.
