  1. CERTI Student

    Very in-depth understanding of radon and how it should be dealt with, as well as, how to measure it. Very well elaborated.

  2. Christian

    I liked the course. It was easy to follow. I never lost interest. The instructor kept you engaged and it felt like the questions from the students were always questions that I was interested in asking myself. Great job.

  3. Ger

    A reliable resource and information that I could continually use. I love how some quiz results gives you not just the answers, but the formula. I highly recommend it.

  4. Jedd

    It is great to have such knowledgeable trainers in the course.

  5. Lynn

    Thank you so very much. This course was thorough! I would recommend it for anyone who is thinking of taking a certification exam. I had taken a radon course in the 1990s and was certified back then but I let my certification lapse because I did not have much radon testing work. This course was a great refresher and I feel well prepared for the certification exam and future testing work.

  6. Ed
