General discussion of radon: its sources, movement and testing; state concerns; list of testing firms. 11 pages. Digital PDF download. IS-24D
Radon, a naturally occurring radioactive gas and its radon daughter (decay) products, has been known for more than 86 years. It was not until about 1983 that a possible connection between radon in homes and lung cancer was recognized by public health workers. This publication discusses what is radon gas, where it occurs, how it is measured, how it concentrates, and testing methods. It also discusses the State’s approach to the radon problem.
