How track etch measures radon gas as clue to U3O8 ore bodies

A dielectric film placed just below the earth's surface is sensitive to alpha radiation, and thus can measure anomalously high levels of radon indicative of buried Uranium ore bodies. The advantages of the Track Etch method include greater sensitivity than gas ''sniffers'', little environmental impact, low cost, and freedom from sophisticated field support. It is proposed that Track Etch could eliminate 30 to 90 percent of the exploratory drilling usually necessary in any uranium exploratory program
