Monitoring of Radon Gas in Air and Water of Iraq: A Review

Radon-222 (222Rn) is a natural radioactive gas with known carcinogenic effects. Iraq’s distinct geology and issues associated with infrastructure account for differences in radon levels between the regions. The review also consolidates evidence from 15 academic and institutional sources on radon concentrations indoors, contamination in water, health effects and approaches to mitigation. Conclusions this study shows that an overall high level of radon exposure exists in different provinces in Iraq, especially within ill-ventilated buildings and sources of water. Based on this study, national radon mapping, public information and regulation enforcement are indicated.
