Radon Exposure Dangers

Radon is a deadly, serious problem that most Americans know very little about. Indoor radon exposure can be reduced, yet many homes go untested. Testing radon levels doesn’t need to be limited to the purchase process. We can perform radon testing anytime and highly recommend homeowners periodically have their homes tested. Without testing, elevated radon levels go undetected.

We hope this information will help to explain the devastating impact indoor radon exposure can have.

  • Radon exposure is the leading cause of lung cancer in non-smokers.
  • Radon enhances the risk of lung cancer in smokers.
  • The US EPA and the Science Advisory Board increased their radon risk assessment in 2004 by more than 50% and now estimate 21,000 Americans die of radon-induced lung cancer annually.
  • 12% of all lung cancer deaths in the US are linked to radon exposure.
  • According to the Science Advisory Board, “radon inhalation is the largest source of collective radiation exposure (and presumably radiation risk) to the U.S. population as a whole.”
  • The US Surgeon General issued a Health Advisory in 2005, warning Americans about the health risk from exposure to radon in indoor air.
  • Because radon is a Class A carcinogen and the second leading cause of lung cancer, the EPA and the Surgeon General recommend all homebuyers test for indoor radon.
