Two methods of radiochemical separation of strontium 90 in picocurie concentrations are described. One is based on classical analytical methods and requires a considerable number of different steps. The other gives a much simpler procedure by use of a chromatographic column. In the latters Dowex 50 type cation exchange resin is employed, and thc eluting agent is 1.2M ammonium lactate at pH 5.5. This separates both the alkaline earths and yttriums avoiding the need for two successive yttrium milkings. Methods of sample preparation are discussed, and a brief note on counting arrangements is given. (auth)
