Radon is a colorless, odorless, and radioactive gas that naturally occurs in rocks, soil, and water. It forms as a result of the decay of uranium, a naturally occurring element in the Earth's crust. While present everywhere, high levels of radon can pose a significant health risk, primarily through exposure in enclosed spaces like homes and buildings. According to the EPA, about 1 in 15 homes in the United States have radon levels above the recommended action level ). This means that millions of Americans are potentially exposed to elevated levels of this colorless, odorless gas, which is the second leading cause of lung cancer in the country.
- Long-term exposure to high levels of radon can increase the risk of lung cancer, particularly for smokers.
- The danger lies in radon's radioactivity, which damages lung cells at high exposure levels.
- The Environmental Protection Agency (EPA) estimates radon as the second leading cause of lung cancer deaths in the U.S. after smoking.
