Safeopedia explains Radiation Sickness
Radiation sickness is most likely to occur in the medical industry. For example, a person who had undergone excessive radiation treatment can often experience side effects, such as radiation sickness. Such occurrences usually consist of minor symptoms of gastrointestinal upsets and nausea. Employees of a nuclear power facility are at risk of accidental radiation exposure. Such accidents usually involve high levels of radiation being passed through the body and lead to more serious symptoms.
