Radon - anyone have experience? Fact/Fiction/Mitigation

[UptaCamp]

What about forced ventilation through use of positive displacement?

Much like HVAC, that is a decent method to reduce radon gas accumulation.

When we built a house in Pennsylvania the builder installed a passive system which included perforated 3 inch pipe under the foundation which teed up to solid 3 inch pipe that ran thru the roof. He said that in the area we were building that usually was enough but if a problem developed it was easy to cut the pipe and install a fan.
I only mention this it might be cheaper to just have the piping installed and then test in a while to see if a fan is needed.

Just curious what made you get the test in the first place?

Realtor suggested we do it because of the unfinished basement.

Ah, yes….
today’s boogeyman, Radon.

Here’s a little update

If it were just me, I probably wouldn't think about it. I have a kid, wife, two dogs and a cat to think about too. If I can reduce the risk of cancer, I'm going to explore the options I have.

Really has nothing to do with humidity. Georgia's geology is the reason for radon beneath homes. Look at all of the granite in the state. Many times uranium/radon is associated with the shallow granite structures in the subsurface. The same reason we have a lot of gold deposits...volcanic intrusions.

And… most builders and concrete subs put down a base of 57stone ( sized granite) before placing concrete. Get my drift….

And it drifts right into the basement it seems.

Mine definitely goes way up when it rains and low when dry out.

Could be the groundwater level rising, bringing it closer to your basement.

I’m sitting on a granite rock, with a rock Quarry a few miles away…I’ll be looking a little deeper into this… I’m testing the water also…

EPA (Federal) used to have radon sampling kits available and free analyses. Not sure if that's still available. I can check.

Not sure if that EPA program is still active, but Georgia may have free or discounted radon kits. Here's some info on who to contact for that:

Find a Radon Test Kit or Measurement and Mitigation Professional | US EPA

Find a qualified radon service professional to fix or mitigate your home. If you have questions about a radon, you should contact your state radon contact and/or contact one or both of the two privately-run National Radon Proficiency Programs

A vented crawl space should allow for accumulated radon gas to migrate outside, however, you are then introducing a possible issue with humidity and mold... whole different discussion.

encapsulation, negative pressure venting, dehumidification, close the vents and seal. I run into so many cabins with crawl spaces wide open and moldy. Talked 2 into encapsulation and what a nice difference

great info,
