Not so accidentally, since it's starting to look like I'm going to be needing
to move some indoor air, outdoors..
I'm not going to try to suck all the air (and Radon gas) out from under my slab.
The first thing I'm thinking of trying, is to vacuum the Radon as it comes
up out of the sump hole.
I'm not sure about the volume of air that will need to be moved,
to suck in most of the Radon that's mixed in with it..
Now, that I can measure the Radon release in nearly real-time, I should
be able to try a simple low-volume vacuum and see any results within an hour or two.
If some flexible sump-pump hose and a small DC fan can get us into the 'safe' range, (or near it)
that might mean that one of those small Heat Recovery units (above) would work..
If the small suction isn't going to be enough, then on to Plan B..

Radon Fan
One of these will move a good volume of air, but would quickly freeze
my basement during cold weather.
So, Plan B will have to incorporate a method of controlling the fan.
Use the Radon detector to control the fan motor.?.
Since the detector will beep a few times, every hour when the level is above 3 pCi/L,
it should be simple to use the beep signal to trigger a 1 hour motor run.
The motor would not run when the level was safe, but if the weather changed,
or anything caused a surge in Radon, it would come on and stay on.
