Radiation sickness is a systematic disease after the body receives a large dose of radiation in a short period of time. Both external and internal exposure can cause acute radiation sickness, but it is mainly caused by external radiation, such as an industry accident. Low doses of radiation, such as X-ray or CT scan in medical examination will not cause radiation sickness. Radiation sickness is often fatal but rare. Notable examples include radiation sickness cases after atomic bombing of Japanese cities of Hiroshima and Nagasaki, fire of 1986 Chernobyl nuclear power plant, and nuclear power plant damage in 2011 earthquake in Japan.
