Radon risk in Hillsborough County, NH

The EPA places Hillsborough County, NH in Zone 2 - a moderate-risk category, with a predicted average indoor radon level between 2 and 4 pCi/L. Zone maps predict the radon potential of an area from geology and existing indoor readings - they do not describe any individual home. Radon is the leading cause of lung cancer among people who have never smoked, and the only way to know your own level is a test kit.

Lead paint risk in Hillsborough County, NH

Census figures show 54% of homes in Hillsborough County, NH were built before 1980, and 22% before 1950.

This is a statistic about the county's housing, not a test of any particular property - if your home predates 1980, a lead swab test is the way to check.
