Frequently Asked Questions

Radon
What is radon?
Radon is a radioactive gas found in every home. It's tasteless, odorless, and invisible. The only way to know how much radon is present is by testing.
Where does radon come from?
Radon comes from uranium in the Earth's crust, breaking down into radium and then radon gas that rises into homes.
How does radon enter my home or building?
Through foundation cracks, walls, pipes, and even well water sources.
Is there a safe level of radon exposure?
There is no safe level. The EPA recommends that mitigation be considered between 2.0 pCi/L and 3.9 pCi/L. At 4.0 pCi/L and above mitigation is strongly recommended. Even exposure to low levels of radon carries risk.
What are the health risks of radon exposure?
Radon is the leading cause of lung cancer in non-smokers and linked to other serious conditions including neurological disorders.
What is a Continuous Radon Monitor (CRM) device?
A CRM device continuously measures radon levels and provides accurate, real-time data over a short period of time. It was specifically designed to provide meaningful results for real estate transactions.
How long does a radon test typically take?
48 hours is the minimum time to determine the radon level. The longer the test, the more accurate the results.
How often should I test for radon in my home?
Every two years or after major property changes such as renovations.
