Which of the following is NOT a method of reducing radon exposure?

• A. Sealing cracks in floors
• B. Ventilating attics
• C. Ensuring sump pumps are covered
• D. Using a radon fan

Answer: (B)

Ventilating attics is not a method used specifically for reducing radon exposure. While proper ventilation is generally beneficial in managing indoor air quality and moisture, radon control typically focuses on the areas where radon enters a home, such as basements and crawl spaces, rather than attics. Sealing cracks in floors, covering sump pumps, and using a radon fan are all effective strategies to minimize radon levels. Sealing cracks reduces the pathways through which radon can enter the living space. Ensuring sump pumps are covered prevents radon from escaping through these openings. Using a radon fan can actively ventilate radon out of the home, decreasing the concentration of this harmful gas indoors. Thus, these methods are more directly related to mitigating radon exposure compared to general attic ventilation.
