ModerateEPA Zone 2ZIP 02093 (Norfolk County, Massachusetts): predicted long-term basement average of 2.6 pCi/L (model estimate), about 1.2× the average US ZIP (2.2) and about 1.5× the Massachusetts average (1.8).
Test ZIP 02093 - the EPA says "consider fixing" in this range
The predicted basement average here is 2.6 pCi/L, in the 2-4 pCi/L band where the EPA recommends considering mitigation. Plenty of individual homes in a moderate area test above 4. Start with a short-term test; if it comes back at 2 or higher, follow up with a long-term test or a continuous monitor.
Already tested at 4 pCi/L or higher? Find a certified mitigation professional (EPA). A mitigation system typically runs $800-$2,500 installed.

Predicted (model estimate). The pCi/L figures on this page are long-term area averages from a peer-reviewed national model built on millions of real radon tests (2001-2021). They describe the typical home in this area - not your home, which can be several times higher or lower. The EPA radon zone is a separate, 1993 county-level classification. How the numbers work.
