Sponsored by the Colorado Department of Public Health and Environment’s Cancer, Cardiovascular and Pulmonary Disease Grants program, this technical manual was developed utilizing over 30 years of experience that its authors and collaborators have had in dealing with radon in Colorado. The purpose for developing the document was to provide a technical resource for radon professionals, builders, engineers and architects allowing them to address radon in a logical and cost-effective manner.  Although it was written for Colorado, the techniques and approaches apply to radon wherever one may find it, which is why we have created this course for a wider application.

To complete the course you should download the Technical Guidance document and read it. You may also want to save a copy of the pdf on your mobile device, so you can access portions of the document or its many graphs and photos to help your clients to better understand what is involved with radon measurement or mitigation. You can also access the document from the CDPHE website at Coloradoradon.info.  As you read the document, we believe you will find there are a lot of useful tidbits and design parameters.

You should also watch the two videos that were produced from recordings of webcasts presented to building officials, radon professionals, builders, and others to explain the many aspects covered within the Technical Guidance. There are two videos: One that covers radon fundamentals and measurement, and a second video that describes mitigation techniques for both single family and larger buildings such as schools and apartments.

Course Includes:

  • Technical Guidance Document
  • Videos
  • Online Quizzes
  • Downloadable Course Certificate
  • 8 CE Credits  (Category 1)


  • Download/Streaming - No course materials will be shipped - everything you need is available to access and download online.
