Thirty-seven (2%) classrooms in 13 (20%) schools had radon
concentrations at or above the U.S. Environmental Protection Agency’s (EPA) recommended action level of 148 Bq/m3(4.0 pCi/L). Number of classrooms had a u-shaped association with classroom radon concentrations. The year the heating, ventilation, and air conditioning (HVAC) system was installed was inversely associated with having classroom radon concentrations at or above the EPA’s recommended action level. Number of classrooms and number of students had u-shaped associations with having classroom radon concentrations at or above the EPA’s recommended actionlevel. Classroom radon concentrations decreased when schools’ HVAC systems were on. Replacing HVAC systems and turning/keeping them on may be effective radon mitigation strategies to prevent
radon-associated lung cancer, especially for small and large schools.
