Have been using AirChek for years with out problems. Always use two kits per test. Generally, “good” results in this area (East TN) run 1.3 to 2.5 — very consistent. The last 3 test results were 0.7, 0.8 and 0.3. Always do a “close house” test for 72 hours. Anyone ever experience reading this low? Comments?
Before offering an opinion, I need to ask… have you had any formal training and from where?
Yes, been certified for 10 years
That wasn’t my question.

That makes your original question even more puzzling. I find it difficult to believe that you weren’t taught about the varying levels of concentration readings. Just in a five mile radius of my service area, I’ve had readings from 0.00 thru 38.7, with an average of 7.6 pCi/L. I have zero reason to question any reading I get, then again, I use a Professional Lab grade charcoal canister, not little sponges hanging off the ceiling!!
Thank you for your input. I’ve used charcoal canisters and Charcoal Liquid Scintillation detectors for the first 6 or 7 years. Switched to AirChek based on recommendations from other inspectors. You seem to have problems with AirChek. Interested in your thoughts. In our area (East TN) a reading of 0.0 is unheard of. Anything less than 0.5 are, for all practical purposes, equivalent to radon levels found outside, in the fresh air. Finding these levels in a home that has been closed for 12 hours and then the proper conditions maintained for 72 hours, does deserve a second look — in my opinion. Thanks again for your help, just trying to do right by my customer. I’ll talk with AirChek on Monday.
Yes . I have had readings this low before. Feel good when a reading is that low. It makes it some what of a SAFE house
