Why It's Important
  • Radon is a naturally occurring gas that seeps into buildings from the surrounding soil. In some cases, well water may be a source of radon.
  • Indoor radon is one of the most serious environmental health problems. It is the second leading cause of lung cancer in the U.S. after smoking.
  • High levels of radon have been found in a number of schools across the country. You can't see, taste or smell radon—only testing can identify it.
What You Can Do
  • Equip new buildings with radon-resistant and easy-to-mitigate features—it is typically easier and much less expensive than to add them after the building is occupied.
  • All schools should test for radon. Conduct tests during cooler months and test all frequently used rooms on and below ground level.
  • To determine if your building site is located in a radon-prone area, consult your EPA Regional Office or state or local radiation office.
  • Read EPA’s Radon in Schools brochure to learn more about radon and what your school can do.
