(a) A secondary radon tester must have both a current, active tester license from the department and a current, active measurement certification from an EPA recognized proficiency program in order to place or retrieve, or represent or advertise that the individual can place or retrieve, passive monitors in a building for radon-222 testing. If an individual loses or relinquishes their measurement certification through the EPA recognized proficiency program, their Indiana license will be immediately suspended, and will remain suspended until the national certification is renewed or the term of the Indiana license expires, whichever comes first.
