Radon Questions, Worcester County
- What level of radon is too high?
- The EPA action level is 4 pCi/L. The Massachusetts Department of Public Health says to fix a home at that level or higher, and to think about fixing it between 2 and 4 pCi/L.
- How common is high radon in Massachusetts?
- The state health department says about one in four homes has high radon, and that high levels are found in every county.
- When should I test?
- The state suggests November 1 through March 31, when windows are shut and levels are usually higher.
- Can I test it myself?
- Yes. Short-term kits run two to three days. Use a certified professional when someone else needs to rely on the result.
- Who should install a system?
- The state health department advises a specialist certified by NRSB or AARST/NRPP. A badly installed system can make radon worse.
- How much does a system cost?
- The state says most cost between $1,000 and $1,500, depending on the house.
- Do new homes in Worcester County come with radon protection?
- One- and two-family homes built since 2015 must include a passive system. Builders don't have to test, so test anyway.
- My house has a system. Do I still need to test?
- Yes. Massachusetts recommends retesting every year or two.
- Is there a limit for radon in well water?
- No federal limit. MassDEP's guideline is 10,000 pCi/L.
- Is this site a radon company?
- No. It's a free request service. We don't test or install, and we're not part of the state health department.
- Who pays for this?
- The service is free for homeowners, buyers, renters, and landlords. No radon company pays us today. In the future, companies may pay to receive requests, which is how the site would stay free.
- What happens after I send a request?
- You get a confirmation email. We review every request and work to connect you with a certified radon professional who serves your town.
