If you've ever taken the NRSB or NRPP radon measurement exam you know it can be grueling. Not everyone passes. While passing is definitely achievable the pass rate is less than average.  Here is why...

This weekend I had the pleasure of being a part of a recent select few asked to rewrite NRPP's radon exam as I am somewhat considered an expert in this field. I can tell you the exam writing process was more grueling than the exam itself. One must have taken a good initial measurement course and include an ample amount of study time in order to pass. Among the group I was with, it was suggested to allow 2 weeks or more for study. There are several documents referenced on exam questions such as the NRPP's Candidate Handbook which covers ethics, two EPA guides - Citizen's Guide to Radon and Home Buyers and Sellers Guide to Radon, along with the recently updated ANSI/AARST MAH 2023 (measurement) and MS-QA 2023 (quality assurance and control) standards. This is a lot of reading! All questions come directly from these publications and the initial course taken (reminds me of a mini-nuclear physics class).  When summarized down to 125 questions  2-3 hours is allowed to take the open book exam (depending on if you choose to be a field tech or a measurement professional). But don't let the open book part fool you. There is not enough time to find the answers if you don't know the material because half the battle is knowing WHERE to find them in WHICH publication.

I am often asked WHY a measurement professional such as a home inspector is expected to know all this material when industry technology allows for just starting and stopping a machine giving the client the radon "number" they need to know. We will cover that in Part 2 coming up.

***have you taken the radon exam? what did you think??
