• Radon is everywhere, see map
  • Naturally-occurring radioactive gas - causes lung cancer
  • Inert, colorless and odorless
  • Naturally in the atmosphere in trace amounts
    • Outdoors: radon disperses rapidly
  • Most radon exposure occurs inside homes, schools and workplaces
    • Indoors: Radon gas becomes trapped indoors after it enters buildings through cracks and other holes in the foundation
    • Can be controlled and managed with proven, cost-effective techniques

Radon Mitigation

Since April 2020, we have observed high levels of radon (>2 pCi/L) which has prompted us to mitigate radon in the air we breathe in the house. This is in spite of having a passive radon mitigation system installed in the house when built.

  1. Seal the concrete basement
    • Gray 1-part epoxy/vapor barrier
  2. Seal cracks and voids
    • Gray 100% Silicone caulk
  3. Add radon mitigation system
    • Radon Fan
    • 3-prong appliance electrical cord
    • 3’ rubber couplers
    • Manometer


Well below action limit of 2 pCi/L
