Radon is a colorless, odorless, radioactive gas that occurs naturally. It can leak into houses and other structures. Long-term exposure to high radon levels increases the risk of lung cancer.
When radioactive metal (radium, thorium, or uranium) decays in rocks, soil, or groundwater, radon gas is naturally produced. Because it evaporates and vanishes outside, the levels are low. However, radon gas can infiltrate indoor spaces through the foundation of structures and get trapped. In their homes, schools, offices, and other indoor spaces, people may inhale radon gas. Every state in the United States has radon. Depending on the types of rocks and soil in each location, radon levels and amounts vary across the nation. The majority of exposure for the general public occurs within the house.
Construction joints or fractures in walls and floors are two possible entry points for that gas into buildings.
* Foundation gaps close to wiring or pipes.
* Construction materials derived from organic resources, like granite.
* Water, particularly that which is drawn from underground wells.
