Can someone please explain to me what an E-Perm Radon tester is? I would like to be able to do radon tests without a second trip. How much does one cost and where can i get one? Thanks.

Hi Michael,
you really cannot avoid the second trip, as the EPA guidelines state that the test needs to be conducted over a 48 hour period, the avdantage that E-perms and CLM's give is that you do not have to deal with a lab to get the results.

“Ouch” $3,000 to $5,000 dollars… Wow… Guess I will stay with the Charcoal Canisters for a while longer. Now that i think about it, I really like Charcoal…

I guess it would be a convenience if they are in a time crunch to close on the house, but waiting four days from the day you start your sample isn’t bad to get results from a lab.

i read in one article that even though you use the machine, they are suppose to be backed up by a canister. Does this statement hold any water? Just seen it in one of my readings. I use the canisters.

Peter:
Calibration is Surface Potential Electret Reader (SPER). The SPER Reader is originally calibrated by the Manufacturer and checked for accuracy Daily with a calibration electret with the reading recorded in a log. If out of calibration, the SPER needs to be sent for service/repair.
This is part of your QA/QC that may be required. Check for specific testing requirements within New Jersey.
