[GSBN] Still ventilating

[John Straube]

Hi there,
Use best practise Radon control: a very airtight enclosure that interfaces with the soil, an air permeable gravel bed / drainage mat around the horizontal and vertical elements respectively, and then connect this layer to a passive stack pipe that runs vertically with no elbows through the living space and projects about the roof ridge and above snow pile depth.
If the radon levels remain high in your spot checks, add a radon fan.

I'm not up on the best approaches to dealing with this, and wonder, in the context of passive survivability and tight buildings, what should we be keeping in mind as best practice?
