Description:
The report gives results of a study to locate candidate houses for a proposed radon mitigation research and demonstration project in North Florida. he effort involved: 1) identification of target geographical areas, 2) radon monitoring in identified clusters, and 3) house characterization. election of target areas with a potential for elevated indoor radon started with a review of a statewide radiation study completed in 1987 and examination of the local geographic pattern observed in a 1986-87 pilot study of the Gainesville area. his effort indicated that North Florida target areas could be selected on the basis of the near-surface occurrence of the Hawthorn geological formation. olunteer houses for radon monitoring in Alachua and Marion counties were obtained by announcing the study in newspaper articles. creening measurements were made in about 400 target area houses according to EPA protocols using a vendor-supplied charcoal collector method. evels observed from these single-sample screening measurements in houses targeted because of their high radon potential ranged from <0.1 to 128 pCi/L. he arithmetic mean was Il. 2 pCi/L and the geometric mean was 6.4 pCi/L. f the houses, 32% were <4 pCi/L, 51% were between 4 and 20 pCi/L, and 17% were 20 pCi/L. esults were similar in the two counties, and distributions were similar in both slab and crawl-space houses.
