Benefits and Costs Analysis of Radon Reduction Strategies Recommended by EPA

Cost-Effective Interventions for Lung Cancer Prevention

EPA developed this analysis to compare updated estimates of costs and benefits associated with the EPA’s program for reducing radon in homes, and to help state or local agencies make informed investments in lung cancer prevention initiatives.

The analysis shows radon reduction programs can substantially reduce the risk of lung cancer. A targeted program that reaches the homes with the highest radon concentrations may be the most cost-effective way to reduce the risks from radon exposure for the greatest number of people.

To address uncertainty, the analysis compares the benefits and costs of radon reduction efforts under several scenarios with varying assumptions about risk, average radon levels, action levels and the effectiveness of radon reduction efforts. The value of future benefits and costs are discounted to estimate their present value.
