Definition - What does Radon (Rn) mean?
Radon is a tasteless, odorless and colorless radioactive gas. It is formed by the decay process of the elements uranium and thorium and constitutes a health hazard owing to its radioactivity. It is one of the densest, most gaseous elements known to man and owing to its radioactivity, extensive research on radon has not been possible to date.
Safeopedia explains Radon (Rn)
When buildings are constructed on soils rich in uranium, the radon resulting from its natural decay process enters and may accumulate in buildings. Sealed buildings and underground workplaces such as basements and mines are particularly prone to radon accumulation. Since the inhalation of radon is linked to a greatly increased chance of cancer, a workplace risk assessment should include measurements of radon levels. High risk radon producing areas are mapped and any workplace located in such an area should monitor radon levels carefully.
