EPA Recommends:

  • Test your home for radon -- it's easy and inexpensive.
  • Fix your home if your radon level is 4 picoCuries per liter (pCi/L) or higher.
  • Radon levels less than 4 pCi/L still pose a risk, and in many cases may be reduced.

Radon is estimated to cause thousands of lung cancer deaths in the U.S. each year.
