Chapter 04 — The North Carolina file
This site imports no North Carolina state roster, so these are current NRPP and NRSB certifications from those programs’ public finders. A national certification is not a state license. We group people by the city on that file. We do not invent neighborhoods. Source: NRPP.
§ 4.1
A city appears only when at least one current listing serves it.
§ 4.3
We have not established a North Carolina radon credential. NC DHHS says: "The North Carolina Radon Program does not require or regulate individual radon certifications." (read 2026-09-08). We publish that as their statement rather than as our own finding, because a programme can be created at any session and this page is checked monthly, not daily. Listings here are current NRPP or NRSB certifications, which are national and are not a state license.
§ 4.4
We have not established a North Carolina radon credential. The state's own radon page says: "The North Carolina Radon Program does not require or regulate individual radon certifications." We read that on September 8, 2026 and publish it as their statement rather than as our finding, because a requirement can be created at any legislative session. Ask the North Carolina radon program if you need today's position.
The 151 listings shown here are current NRPP or NRSB certifications, verifiable on those programs' public finders. The latest record check was October 13, 2026; check each listing for its own date. To ask North Carolina directly, contact catherine.rosfjord@dhhs.nc.gov. If North Carolina does require something we have not found, the agency is the place that will know.
A national certification is never a state license anywhere. For North Carolina we have not established that a state credential exists, and the state's radon page says otherwise in the words quoted above. Treat NRPP or NRSB as evidence of training, and ask the North Carolina radon program what else applies.
