There are no requirements for radon inspection in the state of Colorado. However, the state does maintain a list of radon professionals certified through NRPP or NRSB. The Department does not accredit, certify, recommend, or endorse listed individuals or companies, nor is the Department responsible for work done, or liability incurred, by the individual or company. Listed contractors are certified by the National Radon Proficiency Program or the National Radon Safety Board.
The PHII Radon Measurement Course has been approved by both NRSB and NRPP for initial certification. If you are interested in expanding your business to do radon testing, you can begin by taking the PHII Radon Measurement course. When you have completed the course, you will receive information on how to register for the NRPP or NRSB exam. Both organizations require that you complete an approved course, pass their certification exam, and maintain your certification with continuing education.
Note: NRSB has also approved PHII's Radon Measurement Course for 16 Hours of Continuing Education.
