Three approaches were taken to this objective. One was to use a test house to compare the performance of three different radon mitigation systems: a subslab depressurization system, a subslab pressurization system, and a basement suction system. This house had probes installed outside the foundation to make extensive data logging possible.The second approach was to use a computer program (CONAIR) to simulate the flow of radon-laden soil gas through the soil and through the house, with the same three radon mitigation systems in place. The third approach to assessing subslab ventilation system performance was to test ten contractor-installed subslab depressurization systems in houses in Winnipeg. These houses were visited and measurements of radon concentrations, air temperatures, and system airflow rates were also established"--Exec. summary. |
