Radium in the environment: exposure pathways and health effects

Abstract

Radium is a naturally occurring radioactive element in the environment that can exist as several isotopes. Little information is available on the acute (short-term) non-cancer effects in humans. Radium exposure has resulted in acute leukopenia, anemia, necrosis of the jaw, and other effects. Cancer is the major effect of concern. Radium, via oral exposure, is known to cause bone, head, and nasal passage tumors in humans. The US Environmental Protection Agency has not classified radium for carcinogenicity.
