Radon is a colorless, odorless gas that comes from the natural breakdown of uranium in soil, rock, and water. It can accumulate in homes and buildings, especially in basements and poorly ventilated areas. Because it is invisible and has no smell, the only way to know if radon is present is through testing. Radon is classified as a radioactive gas, which means it can emit radiation as it decays over time.
Radon is significant for health because it is the second leading cause of lung cancer after smoking. When inhaled, radon gas can damage lung tissue and lead to cancer over time. This is particularly concerning for individuals who spend a lot of time indoors in spaces with high radon levels. Long-term exposure to radon can pose serious health risks, making awareness and testing crucial.
In the body, radon does not serve any beneficial function. Instead, its decay products, called radon progeny, can attach to dust particles in the air we breathe. When inhaled, these particles can stick to the lining of the lungs and release radiation, which may damage lung cells. This cellular damage increases the risk of developing lung cancer over time.
It is important for homeowners to test for radon, especially in areas known to have high levels. Testing is simple and can be done with do-it-yourself kits or by hiring professionals. Reducing radon levels can significantly improve indoor air quality and decrease the risk of lung cancer for residents.
