Residential Measurement Provider Qualifications
A person holding the residential measurement credential is qualified to place, retrieve, and interpret the results of a measurement device analyzed by a NEHA certified Analytical Laboratory. This current credential is for residential settings and is appropriate for individuals performing home inspection services.
To attain this credential one must have attended an approved entry level measurement course, and passed a NEHA or U.S. EPA radon measurement exam within the last 12 months; or have been EPA listed as a Measurement Service Provider at some point in 1998. Former EPA listing as an Analytical Measurement Service Provider does not qualify an individual for a NEHA NRPP Residential Measurement Provider Certification. Please call our administrative office if you have any questions (800-269-4174).
NEHA NRPP is currently accepting some state certifications, that are current and in good standing, in lieu of course and exam requirements. Please contact the administrative office at for information.
A simple QA/QC plan indicating the use of duplicates, blanks, and spikes as described in the U.S. EPA Protocols For Radon and Radon Decay Product Measurements in Homes, EPA 402-R-92-003, June 1993, must be maintained and adhered to. (See additional discussion on QA/QC plans.)
The initial application fee of $150.00 certifies an individual for two years. Subsequent renewals will be at a lower biennial fee, currently set at $130 for two years.
An additional credential is under development for measurement professionals who conduct surveys in large buildings or multiple building complexes. The basic residential measurement credential will be one prerequisite for the new credential.
Residential Measurement Provider Using Field Analytical Devices
A Residential Measurement Provider who plans to use devices that provide radon measurements in the field - such as continuous radon monitors (CRM), continuous working level monitors (CWLM) or electret ion chambers (EIC) - may be certified to do so after having fulfilled the following criteria:
See discussions on QA/QC plans and performance testing
A fee of $75.00 will be assessed for each group of device used. "Groups" are distinguished by measurement methodology and by manufacturer.
The device fee is in addition to the base residential measurement fee and runs concurrently with that credential.
Credentials may be amended with additional devices, at any time during a certification period. The assessed fee will be prorated on quarterly intervals for the remaining period of the measurement credential.
