Certifying radon professionals for over 20 years!

NRSB certification is formal recognition of professional excellence based on qualifications, high ethical standards, and continuing education in radon services.

In today’s competitive environment, industry training providers and industry professionals need to be recognized for their knowledge and expertise.

We believe that the quality of the nation’s radon programs depends upon confidence in the integrity of its’ certification process. The National Radon Safety Board (NRSB) stands alone in its’ ability to provide this confidence.

The NRSB provides recognizable conformance to quality and confidence in the radon industry.
