The Maine Division of Environmental Health Radon Section accepts all National Environmental Health Association’s National Radon Proficiency Program (NEHA-NRPP) approved radon courses for both initial training and continuing education. Visit the Maine website for details.
InterNACHI’s free, online “Advanced Radon Measurement Service Provider Course” is both NRPP- and AARST-approved.
I have contacted your state, Rhode Island, but David Spink has not yet responded to my recent request for his review and approval of our radon course. You may want to contact david.spink@health.ri.gov or Regulations: Department of Health
