Understanding Radon: The Silent Threat That Causes Lung Cancer

A Silent Threat: The Impact of Radon on Lung Health



Radon, an invisible and odorless gas, is the second leading cause of lung cancer in the United States. Responsible for around 21,000 deaths each year, this naturally occurring radioactive gas can seep into homes and other buildings, posing a silent yet significant risk.

January has been designated as National Radon Action Month, and the American Lung Association is calling on households across the nation to take action by testing their homes for radon levels. As the gas is produced from the breakdown of uranium in soil and rocks, it can accumulate in enclosed spaces, including homes, schools, and office buildings, especially in areas where the geological conditions are favorable for radon exposure.

Why Testing is Crucial


The only way to know if a home has elevated radon levels is to conduct a test. It is recommended that homeowners test their properties every two years, with many states reporting that radon levels exceed safe thresholds in as many as 1 in 3 homes. DIY testing kits are available, affordable, and easy to use, making it accessible to anyone concerned about their indoor air quality.

As part of their initiative, the Lung Association has partnered with Protect Environmental to offer a limited number of free radon test kits in selected markets. Testing is not only vital when buying a new home but should also be done continuously to ensure the safety of current residents.

Understanding Radon Levels


Radon is measured in picocuries per liter (pCi/L), and experts from the Environmental Protection Agency (EPA) recommend home mitigation when levels reach 4.0 pCi/L or greater. Even some remediation steps should be considered for levels between 2.0 and 4.0 pCi/L. Each household can contact their local radon program or consult certified mitigation professionals to manage elevated radon levels effectively. Many state health departments even provide financial aid or low-interest loans for mitigation projects, making it easier for families to make their homes safer.

Health Risks of Radon Exposure


Radon exposure is particularly hazardous as it is the number one cause of lung cancer among non-smokers. For individuals who smoke, the combination of smoking and radon increases the risk of lung cancer between 10-to-20 times, emphasizing the importance of quitting smoking to improve overall health. Resources are available from the American Lung Association for those looking to quit.

Learn More


The American Lung Association encourages everyone to get informed about radon, suggesting they visit their site for more information and to take the free Radon Basics course to educate themselves further. By understanding radon and its dangers, families can take proactive measures to safeguard their health and that of their loved ones.
