Radon Testing for Homeowners

Radon Testing for Homeowners

What Is Radon

Radon is a radioactive gas that comes from the ground. It's the #2 cause of lung cancer after smoking. You can't see, smell, or taste it.

Testing

  • Short-term test kits ($10-$25) give results in 2-7 days
  • Long-term tests (90+ days) give a more accurate annual average
  • Digital monitors ($100-$200) give continuous readings

Action Level

EPA recommends mitigation if radon levels exceed 4 pCi/L. Mitigation systems cost $800-$2,500 and reduce levels by up to 99%.
