Currently, the NRPP has over 2,300 members who are expected to operate by the ethical practices and national standards set forth by the organization, as well as abiding by local laws and regulations when applicable.

Depending on the state in question and the individual goals of the inspector, there may be benefits for radon professionals who join either the NRPP or the National Radon Safety Board (NRSB), which is another association you can learn more about by clicking here.

The EPA no longer operates its National Proficiency Program, so it is more important than ever that homeowners and other consumers have access to radon professionals certified by a respected association. Radon is still a misunderstood threat to public health, although consumer awareness is growing. For this reason, it is important that members of the radon industry be competent, informed and accessible to the public.

By joining NRPP, you will be gaining access to - and become a part of - a respected community of over 2,300 radon professionals.
