Or, I could listen to Bernard L. Cohen and just ignore the Radon..
Bernard Cohen (physicist) - Wikipedia, the free encyclopedia
Some people think, one of the reasons that Radon concentrations build up inside buildings is because of poor ventilation.
The problem can be severer in really tight houses, w/o good ventilation.
Maybe installing an HRV in the basement would help lower the Radon level,
and perhaps help with bio-hazards that grow in dank basements..
IF, the other 3 sumps are safe, and I only have one Gusher, perhaps a 4" pipe,
right above the sump, or maybe poking down into the sump, might work..
The radioactive by-products of decaying Radon stick to dust (and maybe water vapor).
I'm not sure that pure Radon can actually float up out of a hole, since it's the heaviest noble gas we know of.
I have a feeling that it's going to act like Propane and stay in the lowest areas.
Basically, if you had dust particles in the sump hole, how hard could it be
to drop a disc cover over the sump, (with holes for the pipes and wire),
and suck the dusty air into a pipe and send it outdoors??
I wonder if the entire basement gets filled with Radon, in the morning, when the
oil burner comes on and creates a negative pressure in the basement.?.
It only runs for 20 or 30 minutes each morning. Hey, maybe it's cleaning the air??
