Abstract
A new value of (79)Se half-life was determined by the means of inductively coupled plasma mass spectrometry (ICP-MS) and liquid scintillation counting (LSC) on a sample source isolated from a nuclear reprocessing solution. The procedure used to extract Se from the complex sample solution consisted in liquid-liquid extraction and ion exchange chromatographic methods. The concentration of (79)Se was measured using ICP-MS coupled with electro-thermal vaporisation to eliminate potential isobaric interferences. The activity was measured using LSC after gamma-ray spectrometry to check the contribution of residual radioactive contaminants. From these results, the half-life of (79)Se was found to be 3.77 (19) x 10(5) a.Entities:
