Does Radon Causes Cancer?

Radon releases from normal decay of uranium, thorium and radium. It can seep in through cracks and diffuses into the air. This radon gas decays into radioactive particles and these particles get trapped into the lungs. Long term exposure to radon leads to lung cancer. There has been an increased risk of getting lung cancer with radon exposure in adults and children.

The usual method is to have a vent pipe system and fan installation.
