A ton of information; however, the classroom setting made it easier for me to process. The course is set up for students to succeed. I searched several online courses, and am so glad I chose this one.

I look for a course because I wanted to start a business as a plan B and I didn't expect to learn and be thought so much in dept about radon . I thought I was just going to get taught how to test and how to install not how everything works in detail. but glad it did.

This is a very interesting topic and Doug is easy to watch/listen to. I would have preferred if his videos had a better audio pick-up for the questions from trainees. I'm grateful that he clearly re-stated every question he was asked as I found that very helpful.

A friend of mine proposed the idea of starting a business in radon measurements and mitigation.  Having been in manufacturing sales my entire career this is a bit of a leap of faith.  While I do have some construction background, I certainly do not have any kind of radon mitigation experience.  This course and Doug in particular explained things so anyone can understand not just how radon is harmful but the physics as to why.  


Great course and I would recommend to anyone with an interest in Radon.
