RADIO-ACTIVE GASEOUS GAUGING SOURCE
A Kr/sup 85/ source arrangement for use in radiometric thickness gages is described. The Kr/sup 85/ gas is contained in a stainless steel cylinder with brass end plugs; one plug has a filler tube. This container is inside a shield tube with a window for radiation. The window can be rotated to a shielded position. The pressure in the device can be changed by means of a bellows arrangement to regulate gas density and, thereby, the radiation intensity. Provision is also made for filling and emptying the gas chamber of one or more sources from one line, adjusting to the desired radiation intensity, a separate adjustment for each source. The source window is flexible so that atmospheric pressure variations are compensated. (T. R. H.)
