In its report titled "Overview of EPA’s State and Tribal Indoor Radon Grants Program: A Focus on Activities Conducted During Fiscal Year 2025," the EPA State Indoor Radon Grant Program notes successes of various state programs.
EPA highlighted an experience in New Hampshire. It noted in its report that in New Hampshire, the Rye Public Library found elevated levels of radon in various areas in their facility. After consulting with EPA, the library decided to close the facility for mitigation, which took around a month to complete.
The New Hampshire Department of Health and Human Services assisted the library in expediting their re-opening by loaning them three continuous radon monitors. The program saw an uptick in test kit requests in response to news articles that detailed the library’s experience.
