Care must also be taken in deciding where to locate the vent stack which will exhaust the gases collected from beneath the structure. The emissions at the stack contain concentrated doses of radon which will measure in the hundreds of picocuries, as well as other soil contaminants. Placement of the exhaust stack must be at least 10 feet above the ground and ten feet away from windows, and exhaust stacks that might permit the gas to re-enter the structure. The gases will dissipate safely beyond ten feet in open air.
Consequently the design of your home is going to have an impact on how and where a radon system is installed
