Radon Challenges – Gnarly Tales from the Field – Part II (CERTI-8000)

(61 customer reviews)


CERTI is pleased to present PART 2 to Gnarly Tales one of our most popular courses for both measurement and mitigation professionals. Recorded at the 2022 AARST conference – an excellent course for learning how to deal with difficult situations.

SKU: C-8-108 Category: Certified By:


For those that enjoyed CERTI’s original Gnarly Tales the good news is that the series continues.  The bad news is that more weird and challenging situations continue to arise as measurement and mitigation professionals address radon in more and different situations.  This course delves into challenging situations that have been encountered and how they have been identified, diagnosed and successfully mitigated.  Included are cases where HVAC systems, weather, permeable soils, tight soils, complex foundations and other surprises have presented challenges requiring more in-depth investigations beyond simple “poke and hope” approaches.  The course is taught with the assistance of experienced radon professionals presenting real world cases-with solutions.

Course Includes:

  • Video Recordings of Classroom Presentation at 2022 AARST Conference
  • Online Quiz
  • Resources
  • Downloadable Course Certificate
  • 8 CE Credits  (Category 1)

    I always enjoy the CERTI courses. The information is more relevant to day to day mitigation. Quizes are designed to test for understanding rather then trip-up the test taker.
