This new course was presented at the 2017 Region 8 Annual Conference - C-16-108 - Addressing Radon in Daycare Facilities, Schools and Large Buildings (CERTI-323) is a great new 16 CE hour course - This course takes radon testing to the next logical step in developing a considered approach to addressing radon concerns that have been identified during a building survey.  Whether a survey involves a daycare facility, a school, or an administrative building, there is often a need, as dictated by the availability of resources versus the severity of the problem, to have a plan of attack.
