Did you know that approximately 1 in 4 homes tested for radon through this program tests above 4 pCi/L (picocuries per liter)? 

Selected statistics from 2015-2020:

  • Percentage of tests over 4 pCi/L: 26%
  • Highest test result: 179 pCi/L

For your lungs, a radon level of 40 in your home is equivalent to smoking 4 packs of cigarettes per day.

Protect your family by testing for radon in your home. 

EPA advises that if the radon level detected in a home is between 2 and 4 pCI/L, steps should be taken to reduce it to below 2 pCi/L. EPA has established 4 pCi/L as an action level at which one should initiate measures to mitigate the amount of radon in the home.  However, there is no safe level of radon.
