Hi Brad, First, Welcome to the org. and the board! I totally agree with Nick on the Eperm issue and have been using them for 2 years. Although the initial layout is quite costly, It was recovered in a very short period of time (approx 3-4 mths) in my case. It is figured to cost less than $2 per test and deliver quick results which is very popular due to time frame limits on real estate transactions. On the positive side, I have EPA documentation showing Eperms to be even more accurate than CRM’s (Continuos Radon Monitor), but, as Nick states, on the down side is the tampering issue. The self-made Eperm cage listed here is one way around that, or, I personally use a lockbox together with tamper resistant tape and the unit cannot be moved without detection. As far as covering it up! I also have a way around that I cannot mention here. As far as people venting or opening the structure to dissipate the radon, again, tamper resistant tape on doors and windows is the only deterrent. If you need more info, please feel free to contact me directly. Hope this helps. BW
