How long does a professional radon test take?

A standard short-term radon test takes a minimum of 48 hours under closed-home conditions. The EPA recommends at least 48 hours for reliable results, and most professionals use continuous monitors that record hourly readings throughout the test period.

What radon level requires action?

The EPA recommends taking action to reduce radon levels at or above 4.0 pCi/L (picocuries per liter). However, the EPA also notes that radon levels below 4.0 pCi/L still pose some risk, and homeowners may want to consider mitigation at levels between 2.0 and 4.0 pCi/L.

Is a DIY radon test as accurate as professional testing?

DIY test kits can provide a general indication of radon levels, but professional continuous radon monitors (CRMs) are significantly more accurate and detailed. Professional tests provide hourly readings, are tamper-resistant (important for real estate), and are administered by certified technicians who ensure proper placement and conditions.
