The reason suspended floors with a 'sump' arrangement work is because
radon is very heavy, and will collect at the lowest point - even if it

Ah. I hadn't thought that through. It has to be heavy, being radioactive...
Ventilation is the way to deal with it though.
Agreed - far more practical to install in an existing house.
Can Radon get through plastic DPM?
Only to a small degree.
