ABSTRACT:
A system for extracting radon and other gases from a subterranean cavity beneath a floor slab and venting of collected gases to the atmosphere is provided which conducts cool, naturally occuring radon and other gases under high vacuum across a vacuum pump motor for cooling the motor. A vacuum pump is disposed within a housing chamber under vacuum. Cool gases within the housing chamber thereby conduct heat generated by the pump motor to the atmosphere.
