New Hampshire Public Health Tracking Radon Results

by Margaret Henderson

The “Granite State” has an average radon exposure potential that is 44% higher than the national average due to the geology of the state. Of the homes tested, 30% had elevated radon, with the median concentration ranging from 5.9-9.8 pCi/L (varying over various counties and areas of the state). The recommended action level (USEPA) is 4 pCi/L. Southeastern and eastern New Hampshire counties have the highest percentage of homes with elevated radon levels.
