The home we put a purchase agreement on has elevated levels of Radon (13.4pCi/L). Not horrible, but much higher than the EPA recommend level of 4 or less. They want to put new laws that new homes must be 0.4 or less. I was doing some reading, looks like it's not a real big deal to fix, the mitigation systems usally cure the problem. But installtion can be as much as $3000. Soil suction, under slab suction, doesn't sound pretty. Just curious as to what your expierence with Radon and the various mitigation systems they have.
