NRPP is developing a new credential for professionals who are responsible for measuring radon in large commercial buildings such as multifamily and other residential occupancies, schools, commercial buildings and other non-residential occupancies.

If your work involves measuring radon in large commercial buildings, or supervising others measuring radon in large commercial buildings, please complete the following survey and tell us about your job responsibilities.

Your responses will be kept confidential. Responses will be aggregated and the results will be used as the foundation for building the new Commercial Radon Measurement Professional certification program.

The survey should take 20 minutes to complete. If you are currently certified you may claim one (1) continuing education credit (CE) toward renewal of any NRPP certification for completing this survey. To do so, you must respond to all questions and provide your contact information at the end of the survey. Incomplete surveys will be denied CE. One CE maximum will be awarded. Please allow up to one week to see the CE reflected in your NRPP certification account. https://www.surveymonkey.com/r/LH2LMN9
