The rule

Does Virginia license radon professionals?

Virginia's radon program page, checked on November 3, 2026, says:

The Code of Virginia requires that Radon testers and mitigators be currently certified by either the National Radon Proficiency Program (NRPP) or the National Radon Safety Board (NRSB).
VDH Radon Program, read November 3, 2026

EPA's state contacts page lists Virginia among the states with radon credentialing programs. Licensing is done by the state, not by the national programs, and EPA requires states that receive radon grants to give the public a list of only those providers credentialed by the state or by NRPP or NRSB.

Before you hire

How to check a credential in Virginia

  1. Virginia's own list

    Start with the Virginia Department of Health, Indoor Radon Program. Licensing is done by the state, so its list or search says who may legally work in Virginia.

  2. NRPP's search

    The National Radon Proficiency Program's search finds its Certified Mitigation Specialists and Certified Measurement Professionals by area, by name, or by the 6-digit NRPP ID number a professional can give you.

  3. NRSB's search

    The National Radon Safety Board's search finds a professional in your area, or confirms that a named professional is NRSB certified.

  4. The ID card

    The programs usually issue a photo ID card showing the holder's qualifications and its expiry date. Ask to see it, and if in doubt, check with the body that issued it.

Hiring

Hiring in Virginia
