Just got the bad news.. 48 hour test results are 9 pCi/L
I switched to long-term mode, muted the hourly warning beep (when over 3 pCi/L)
and moved the detector back down on the PVC pipe, where 39 pCi/L reading registered.
Just want to see if that reading was a fluke or, will it zoom up there again.
Now, I've got to start doing some real planing.
Edit:
One hour later, it's up to 10 pCi/L
Edit: 19:20 now it's 11 pCi/L
Edit: Dec 4, 12:25 13 pCi/L
Edit: Dec 4, 16:15 14 pCi/L (As of now, the senor has been lowered into the sump)!
