Introduction
Radon (²²²Rn) is a naturally occurring, colorless, odorless, and tasteless radioactive gas produced by the decay of uranium in soil, rock, and water. Chronic exposure to elevated radon concentrations is the second leading cause of lung cancer in the United States, and the primary cause among non-smokers. Iowa is designated by the EPA as Radon Zone 1, predicting average indoor radon screening levels greater than 4 pCi/L (picocuries per liter), significantly exceeding the national average. The geological composition of Iowa, characterized by uranium-rich glacial deposits and limestone bedrock, contributes to this heightened risk. Radon enters buildings through cracks and other openings in foundations and can accumulate to hazardous levels indoors. The concentration of radon within a structure is subject to temporal variation, influenced by factors including soil moisture content, barometric pressure, ventilation rates, and building construction.
Given the established health risks associated with radon exposure and the documented prevalence of elevated radon levels in Iowa residences, the decision to conduct radon testing during real estate transactions presents a critical juncture for prospective homebuyers. This chapter explores the scientific basis for radon risk assessment and mitigation, reviews relevant state and federal guidelines pertaining to radon disclosure and testing in real estate, and elucidates the ethical and legal obligations of Iowa real estate agents when advising clients on this issue. The educational goals of this chapter are to equip real estate agents with the knowledge necessary to:
Comprehend the scientific principles underlying radon generation, transport, and health effects.
Recognize the factors contributing to elevated radon risk in Iowa residential properties.
Articulate the importance of radon testing to clients in a clear and scientifically accurate manner.
Outline the standard protocols for radon testing, including short-term and long-term measurement methodologies.
Advise clients on appropriate mitigation strategies should elevated radon levels be detected, including referencing qualified radon mitigation professionals.
Identify and adhere to all applicable Iowa regulations and professional ethical standards related to radon disclosure and testing in real estate transactions.
