Description:
The report gives results of a new house evaluation of potential building design and construction for the control of radon in Marion and Alachua Counties, Florida. During the project, which began in March 1992, the construction of 14 new houses, built in accordance with the Draft Florida Standard for Radon-resistant Building Construction (referred to as the Draft Standard) was observed. Nine houses referred to as Type A were constructed according to the Draft Standard, and five houses referred to as Type B were provided with sub-slab ventilation systems; however, the Draft Standard's construction quality sections were not monitored. The purpose of Type B was to evaluate the effectiveness of compliance with the Draft Standard criteria. Furthermore, Types A and B provided some basis for comparing various aspects of relevant radon technical discussions. After completion of construction, all houses were tested for indoor radon level. Only one house needed a mitigation fan. Later, the indoor radon levels in all houses were found to be under the prescribed Florida Department of Community Affairs (DCA) limit of 4 pCi/L.
