The Szilard-Chalmers process is a method for producing radioisotopes whose specific activity is much higher than that obtained in a simple metal or salt target. A number of Szilard-Chalmers processes were investigated and simple and effective procedures devised for the following radioisotopes: 38-min CI/sup 38/, 2.6-hr Mn/sup 56/, 12-hr Cu/sup 64/, 14-hr Zn/sup 69m/, 27-hr As/sup 76/, 36- hr Br/sup 82/, 4.6-hr Br/sup 80, 27-hr Sn/sup and 25-min I/sup 128/. The target preparation, separation scheme, exposure level, and expected minimum yield and enrichment are given-. The yields are generally independent of exposure up to at least 100 kw-hr (2 x 10/sup 15/ nvt) while enrichments increase with decreasing exposure. (W.L.H.)
