"The project had the objectives of studying the effectiveness of subslab ventilation systems in reducing indoor radon levels, and of assessing their potentials for creating foundation problems, wasting energy, and creating troublesome or dangerous indoor depressurization. To achieve these objectives, a computer program was used to simulate the flow of air and radon through a house and the soil surrounding it for fifteen cases. These cases considered different combinations of three radon mitigation systems (subslab depressurization, subslab pressurization, and basement suction), a large and small separation width between the basement wall and backfill, a soil air barrier at grade level, and two subslab venting system flow rates"--Abstract, p. i.
