A method is described whereby radiochemical analysis for the long-lived fission products Ru/sup 106/, Sr/sup 90/, Cs/sup 137/, and or biological material. Carriers are added and the material is fused at 550 deg C with KOH, KNO/sub 3/, and K/sub 2/CO/sub 3/. Ruthenium and ccsium are extracted with water, strontium and cerium remaining in thc melt. Ruthenium is extracted into carbon tetrachloride as ruthenium tetroxide, cesium is absorbed on Duolite C-3 cation- exchange resin from alkaline solution, strontium and cerium are extracted from the melt with acid, cerium is precipitated as the hydroxide and strontium as the carbonate. The elements are precipitated, weighed, and counted according to standard procedures. (auth)
