Radon Training
PHII Radon Training / Continuing Education

The National Radon Safety Board (NRSB) is an organization that maintains a network of certified radon professionals, including those specializing in radon measurement, mitigation and as radon laboratories. The NRSB maintains standards that its members adhere to, which you can view by clicking here.

The NRSB has members all over the United States 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 NRSB or the National Radon Proficiency Program (NRPP), which is another association you can join if you so wish. You can check individual state requirements by clicking here.

We recommend visiting the NRSB's official website for complete information about the organization, but here is some basic information: 

How Do I Become A Member Of The NRSB As A Radon Measurement Provider?

You must:
  • Submit evidence of successfully passing approved training course, such as our Radon Measurement Course.
  • Submit evidence of passing the NRSB exam. The NRSB exams may be taken either in conjunction with approved training programs, or through a system of individual proctors. Exam guidance, proctor qualifications and exam order information are available here.
  • Submit an application for Radon Measurement.
  • Upon acceptance, pay a fee.
  • Applicants must specify which devices they are using and list the NRSB device code on the application.

What Benefits Are There For Joining NRSB?

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 NRSB, you will be gaining access to - and become a part of - a respected community of radon professionals.
