C-4-110 - Addressing Radon Decay Products - Another Tool in the Tool Box (CERTI-324)

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.

It is well known the mechanism by which radon exposure increases the potential of lung cancer is alpha release from the short-lived decay products of radon and the amount of these decay products available for respiration can vary due to air circulation rates, particulate levels, etc.  This course explores from a practical standpoint how radon decay products are measured and how RDP reduction can enhance soil gas remediation by reducing radon risks to very low levels.

This course was presented at the request of the Canadian Association of Radon Scientists and Technologists at its Annual Meeting in Banff, Alberta on April 23, 2017.  Although provided to a Canadian audience it has application for radon professionals around the world.

This course was excellent and gives the mitigator other options to look at in difficult houses, also reminds us to look at radon as its decay products and not just a soil gas.

Very good technical course and well structured from start to finish.  Did an excellent job providing the information in a way that makes it easy to grasp.  Thought the quiz was challenging, but suited the content of the class well.  Definitely have to understand the course material/presentation in order to pass the quiz.

Awesome course! I didn't realize how much air movement and filtering would help. It appears that air movement causes more plating out and filtering captures some of what hasn't plated out.The info is as the course topic suggest, Another Tool in the Tool Box. I cant keep up with Doug and his math conversions to WL since we rarely use it here in the US. I'm going to start paying more attention to these issues while doing Building Investigation and suggestions for repairs.
