Biological Impact of Radon Gas on Juvenile Cells and Children

Radon gas (Rn-222) is a naturally occurring radioactive noble gas produced by the decay of uranium and thorium in the earth’s crust. It is the leading contributor to natural background radiation exposure indoors. Due to their developing tissues and higher mitotic rates, children and juvenile cells are particularly susceptible to radon-induced damage. This article reviews the biological mechanisms of radon toxicity, its impact on juvenile cells and children, epidemiological findings, and public health considerations.
