This course is a required review of the current SGM-SF Standard.


Conducting Radon Surveys in Schools: Course ID# CERTI-330 6 Hours / 6 Cat-I Credits

Description:  Conducting a radon survey in a school is a little different than testing a home. In addition to the thermal stack effect, a building’s heating ventilation, and air conditioning system (HVAC) complicates the situation by reducing indoor radon or increasing it if it is improperly maintained. Add to that varying operating conditions that exist when a building is occupied versus unoccupied make the interpretation of measurements an interesting, but not overwhelming challenge -if done correctly.

This course walks through the unique considerations presented by schools as well as a commercial building that has central HVAC systems. A student completing this course should be able to:

Plan a radon survey
Implement a communication plan for staff and parents
Be able to place and retrieve devices
Implement a quality assurance and quality control plan
Interpret the results and determine appropriate follow-up action
Develop an initial response plan should elevated levels be found.
This course is designed for radon professionals who wish to conduct radon surveys as well as building managers who may be charged with overseeing such a survey.
