This course, approved by the NRPP for 4 educational CE credits, expands the radon measurement professional’s skills beyond testing residential structures to be able to take advantage of the expanding market of conducting surveys in large buildings such as schools and apartment buildings.Testing large buildings entails a lot more than taking using more test devices. It is necessary to be able to convey to the client why multiple locations need to be tested; be able to implement communication plans for occupants; and to understand special approaches to interpreting results to provide the best value to the client while shielding you from downstream liabilities.This course, recorded at a live classroom session at the National Radon Conference in Vancouver in April, 2015 deals with all of these issues and more. It also provides sample notices, log sheets and other tools you will need to fully implement a large survey.  You will be able to watch and listen to the lecture as well as benefit from the poignant questions posed by the live audience, consisting of radon professionals just like you.
