Approximately how many lung cancer deaths per year are related to inhalation of radon and radon decay products, according to the EPA?

The estimate of approximately 21,000 lung cancer deaths per year in the United States related to the inhalation of radon and radon decay products is based on comprehensive studies and statistical analyses conducted by the Environmental Protection Agency (EPA). Radon is a naturally occurring radioactive gas that can accumulate in homes, particularly in lower levels such as basements. It is a significant risk factor for lung cancer, especially for individuals who smoke, as the combined risk of radon exposure and smoking increases the likelihood of developing lung cancer substantially.

The EPA's estimation considers various factors, including population exposure levels, the radon decay product concentrations in homes, and data on lung cancer incidence rates. This figure underscores the importance of radon testing in homes, particularly in regions known for higher radon levels, and emphasizes the need for mitigation strategies where high radon concentrations are found. The statistic serves as a critical reminder of the health risks associated with radon exposure and highlights the importance of awareness and preventive measures in maintaining indoor air quality.
