The Certi radon measurement coarse was recommended to me by Other Measurement professionals. The coarse provided information great information. It allowed me to continue to review and retest. It would be great if all of the test content was in the course work, we had to do flash cards, study guide and purchase other material to pass the exam. There is a lot of material in the exam that is not covered in the course.

Very Informative. I've been doing Radon testing for 20 plus years and thought I knew everything about Radon. I was wrong and I actually knew very little about Radon.

Doug is a very good instructor and the audio/video quality of the lectures were very good as well. Some questions in the quizzes did not pertain to that specific topic.

The course is great for preparing you for the NRPP exam! I'm in CO and the exam covers way more than I personally need to know as I will just be placing canisters to be analyzed by a lab, but we need to be certified to do that as of July, 2022. So this course has been amazing in helping me prep for that!

Topic five was very long.  The video bounced all over the place, making taking notes a challenge.

I might suggest introducing each device before comparing them to each other.
