ABSTRACT:
Radioactive gaseous decay products emanating from a buried deposit of uranium or other radioactive ore migrate upwardly through the earth and are exhaled into the atmosphere. These products may be trapped at the surface in a series of low profile, dome-shaped plastic shelters 5 to 20 feet in diameter. Radiant energy permeating each shelter cover heats the soil beneath the enclosed surface area to accelerate the escape of gas through the soil. The air confined within the shelters is continuously recirculated over the exposed surfaces of a plurality of highly adsorbent discs. After equilibrium decay conditions are reached, the discs are analyzed to determine the radioactivity of the discs, which is proportional to the concentration of radioactive gas in the vicinity.
