The new radon sensor displayed 1.8 pCi/L after 48 hours, upstairs in my PC room.
I've moved it downstairs beside the other sensor (which is staying at 4 pCi/L),
so I can get a comparison of the units.

1.8 is good news, since my PC room is directly above the P2 radon source!

We are seeing 2 pCi/L and 1.9 pCi/L displayed since this morning.
There is a little slow up and down on the new unit. (Up and down 1 tenth).
The Pro-3 seems to up-date more often than the older Pro-2 model,
Which does a round-up function, since it has no decimal point.

This is all good news. Now I can take my time and pick out the right hardware for this job.
I'm seriously considering trying one of the low powered radon fans.
I keep wanting to say Radon Pumps for some reason.

Now, I feel we can wait until we get some nice spring weather,
before starting the outdoor part of the job.
In the meantime, I'll be keeping a close eye on the radon levels..

Edit 1/5/2012:
It's been 20 days now, and the radon levels have stayed low, mostly under 2.0 pCi/L meaning the seal is holding.
