Radon Challenges – Gnarly Tales from the Field


This course is offered in partnership with CERTI. 

  • Interpreting radon measurements or mitigating buildings with radon concerns is not always as easy we would like them to be.
  • Experienced radon professionals from both sides of the profession occasionally will run across a situation that doesn’t necessarily fit the simple diurnal cycles that affect stack effect or houses that don’t adhere to the simple mitigation diagrams we often see in texts.
  • @ HomePrep is a National Leader in online education. With over 100,000 satisfied students and a course catalog of over 1,000 classes, we are here to help you – Invest in Yourself.
