I’m wondering how everybody performs their radon sampling. I’ve always used the sampling canisters from Pro Lab, and have not had an issue in the year and a half that I’ve been involved with radon sampling. Two weeks ago however, I had a sampling come back with measurements of 10.6 & 9.1pCi/L, producing a 9.9pCi/L average. This of course is not a favorable reading.
The sellers challenged the reading and ordered their own, which came back at 2.5pCi/L. The buyers agent, now facing opposing readings, orders her own sampling, which comes back the same as the sellers (2.5 pCi/L). So, the buyers agent calls me a gives me all of this information and states her case for a full refund of the radon sampling that I performed for her client. Of course, I’m fairly embarrassed and quickly agree to refund the money and make a alot of apologies. Come to find out, both of the other inspectors are using continuous electronic devices, verses the canisters that I use from Pro Lab.
My question to everyone is this;are the sampling canisters like the ones I use from Pro Lab anywhere near as reliable as the electronic devices such as Sun Nuclear’s 1027?, should I stop using the canisters and pony up for an electronic device?, how possible is it that Pro Lab screwed up the testing?
Hmmmmm. Lots of questions I know, but getting a false reading like this has left me kind of rattled w/r/t radon sampling. If anyone can offer their opinions as far as which method is more prefferable or how reliable they think the canisters are, I would really appreciate it.
