Radon Facts & Resources

  • Radon decay products produce alpha particles that are harmful to the tissue in the lungs.
  • Radon is the 2nd cause of lung cancer after smoking, killing more people than drunk drivers.
  • There are no safe exposure levels to radon. The EPA’s recommendation of 4.0 pCi/L as a trigger for remediation is based on technology and economics, not on safety.
  • Buildings with Radon can be fixed – there are many ways of reducing the radon levels inside a building.
  • The EPA recommends long-term sampling performed every 2 years after a successful remediation system has been installed.
  • For more information:

Short- and Long-Term Testing

Short-Term (3-7 days)

  • Gives a “snapshot” of the radon concentrations under “worst case” conditions at the time of the sampling.
  • Provides an indication of radon potential. This method is used in real estate transactions and to provide a cursory idea of the radon potential.
  • Test performed under normal living conditions.

Long-Term (90-360 days)

  • Determines radon levels of the building as used by its occupants.
  • Determines average radon levels over longer periods of time under “normal living conditions” for the building with those occupants.
  • Test requires “closed house” conditions, where building is closed except for normal entry/exit.
