Note:  As of 9/30/98 EPA no longer runs a National Radon Proficiency Program.  Some states "regulate" providers of radon measurement and mitigation service providers and measurement devices by requiring registration, certification, or licensing.  Some of these states issue identification cards, call your state to learn more.  You can also contact the National Environmental Health Association's (NEHA) National Radon Proficiency Program at 1-800-269-4174 (radonprog@aol.com) or, the National Radon Safety Board (NRSB) at 1-866-329-3474 (info@nrsb.org) or visit EPA's radon proficiency page for more information on finding qualified radon service professionals.
