EPA (Environmental Protection Agency) Program to Demonstrate Mitigation Measures for Indoor Radon: Initial Results

摘要

The paper gives initial results of an EPA program to demonstrate mitigation measures for indoor radon. EPA has installed radon mitigation techniques in 18 concrete block basement homes in the Reading Prong area of eastern Pennsylvania, all designed to demonstrate techniques which would have low to moderate installation and operating costs. Where major openings in the block walls can be closed effectively, suction on the wall voids has proved to be extremely effective. However, where major openings within the walls are inaccessible, it is more difficult and/or more expensive to develop adequate suction on the void network, and performance is reduced. Testing is continuing to demonstrate how to achieve high performance with wall suction in homes with such difficult-to-close walls.
