Radon Fundamentals


The Radon Fundamentals course provides tribes with an introduction to the mechanics of radon, examples of how tribes are addressing radon, and possible funding opportunities. This course does not provide radon certification.

The presentations in this course were originally developed as webinars in February and March 2016 in collaboration with US Environmental Protection Agency (EPA) Region 9 Tribal Indoor Air Quality and Health Network and staff from Spokane Tribe Department of Natural Resources, Navajo Nation EPA, Taos Pueblo Tribal Housing Office, University of Alaska Fairbanks, and the US Department of Housing and Urban Development (HUD). This online course is equivalent to 0.7 continuing education units (CEUs) and requires approximately seven hours of total learning time. CEUs are earned by completing the following course modules; course content is also available on-demand for the casual learner:
