Overview

radiation sickness


Show Summary Details

Quick Reference

An acute illness caused by extreme exposure to rays emitted by radioactive substances, e.g. X-rays or gamma rays. Very high doses cause death within hours from destructive lesions of the central nervous system. Lower doses, which may eventually prove fatal, cause nausea, vomiting, and diarrhoea followed after a week or more by bleeding and other symptoms of damage to the bone marrow, loss of hair, and bloody diarrhoea. Some of the milder symptoms can occur after radiotherapy during treatment of cancer.
