ARE Exam Prep: Radon for PA | ARE Lab

An overview of the risks associated with radon, a radioactive gas originating from the natural decay of uranium in soil, emphasizing that it can accumulate inside buildings. It explains the relationship between a building’s structure and the likelihood of radon infiltration, noting that while homes with a basement or cellar typically have higher concentrations due to increased soil contact, even structures without a basement, such as those with a slab-on-grade foundation, are susceptible. The text also mentions that houses built on pier and beam foundations with ventilated crawlspaces generally face lower risks. Finally, the source concludes that no home is entirely risk-free and advises following the U.S. EPA's recommendation to conduct radon testing in all residences, regardless of foundation type, suggesting that incorporating radon-reducing design features during construction is the most reliable preventative measure.
