This paper presents a radiochemical separation procedure of79Se from high level liquid radioactive waste, with nitrobenzene extraction and with sulfur dioxide precipitation. The procedure gives a chemical yield of selenium greater than 60%, and satisfactory decontamination is observed for all the relevant radioactive nuclides. Liquid scintillation counting were used for the measurement of79Se radioactivity. The79Se samples obtained from the procedure were used successfully in79Se half-life detemination.
