Technologies that reduce exposure to radon in buildings

Radon mitigation technologies using sub-slab depressurization have been demonstrated for many years but may not be practical for some applications due to cost or building characteristics. Of particular interest are alternatives to sub-slab depressurization radon mitigation strategies and technologies for low-income housing or for high-rise buildings, lower cost alternative materials for soil gas collection plenums in new construction, and effective methods for mitigating radon in well water. Important parameters include low cost of installation and operation, ease of maintenance and operation, and feasibility of retrofitting the proposed technology.
