Yeah, I'm going to have to do something. Not sure exactly how big the problem is at this point.
But, I'm pretty use my next results are going to tell the story.

I'll have another reading in about 18 hours. If it's high, I'll have to repeat my
survey of the other 3 sump holes. I'll want to know if the problem is just in this one area.

I've read that an increase in the water table can give you Radon surges.
If I'm lucky, maybe we won't see a continuous high level of gas from that hole.

If there is a lot of Radon being released in that one area, I'll try a quick fix,
so we won't have to be worried about even short exposures doing chores in the basement..

I'm pretty sure I can make a cover that's tight enough, so a suction hose
can be used to suck out the gas. The goal will be =< then 3 pCi/L

Finding this much Radon has been a real shocker, since I've been monitoring
the basement at least once a year, for the last 6 or 7 years.
That 39 pCi/L reading is just unbelievable.

Now that we have three new sump holes, I'll have to start a continuous test mode.

I may buy a new detector, so I can check the calibration of this unit,
and increase the speed of testing the whole basement. (And upstairs).
Sending the unit back for calibration cost $75. That's half the price of a new one.

Edit:
Or, we could move to Southwest Texas!!!
