Multifamily Radon Measurement

Live Webinar


The Radon Live Webinar consists of one 8-hour session, from 8:30am - 5:30pm (ET). The online session allows you to attend the class from the comfort and ease of your own home, but with the real time participation for a robust interactive curriculum. The webinar has a limited number of openings to further facilitate this intimate learning experience for all students involved.



This 8-Hour class includes AARST-NRPP Workbook (required for Add-on Certificate) and ANSI-AARST Standard. Must be NRPP-certified in radon measurement to earn the Advanced Certificate. Radon testing in multifamily buildings has gained increasing importance since a 2013 HUD policy change requiring testing them for radon if HUD-financed. The policy specifically cites the ANSI-AARST Standard on testing multifamily buildings. This class focuses on the “ANSI-AARST Standard: Protocol for Conducting Radon and Radon Decay Product Measurements in Multifamily Buildings” and is intended to help to educate you on the standard and the HUD requirements. It will also prepare you for the new AARST-NRPP add-on certification. This add-on will distinguish measurement professionals who have training and expertise in this specialized field. Testing protocol specific to multifamily buildings will be emphasized to help the radon professional perform a critically important and legally sensitive regimen that is integral to the ownership and property transfer of HUD-financed multifamily residences.


Webcam and microphone are required for the class.
