Facts About Radon
- Radon is the second leading cause of lung cancer in the United States.
- It is generated from the radioactive decay of uranium.
- The half-life of radium is about 3.5 days and, since radon is produced when it decays, large amounts of radon can build up rapidly.
- Radon is the heaviest inert gas that naturally occurs.
- In every square mile of surface soil, down to the depth of six inches, one gram of radium occurs naturally.
- The seven ways that radon seeps into your structure include cracks in solid floors, construction joints, gaps in suspended floors, gaps around service pipe feedholes, cracks in walls, water supply or cavities inside walls.
An example of radon is when radon gas seeps into a building through the floors, causing health concerns including lung cancer.
