New Jersey requires businesses and individuals who test for or mitigate radon in buildings to be certified by the Department of Environmental Protection, with exceptions such as a person working on a building they own. The state's rule says each certification credential lists a certification number and dates, so ask to see it. Check the credential on record, and check the agency's site for current requirements.
