Certification

The US EPA and your state health department strongly recommend that ALL homebuyers, sellers and owners have their home tested for the presence of indoor radon. Hiring the services of Radon Measurement Professional certified by the National Radon Proficiency Program (NRPP) is the only way to ensure that test is performed according to ANSI-AARST Standard Protocol for Conducting Measurements of Radon in Homes.

Homes with elevated radon can easily be fixed in accordance to the ANSI-AARST Soil Gas Mitigation Standards for Existing Homes by an NRPP Certified Radon Mitigation Professional.

The National Radon Proficiency Program serves as the credentialing and certification division of AARST and is recognized as the nation’s leading certification program for radon professionals. Currently, NRPP has over 2,800 certified professionals qualified in measurement, mitigation, and as radon laboratories.
