摘要
Liquid samples of Zr-93 were isolated from high level liquid wastes (HLLW) by means of silica gel adsorption combined with tri-N-butyl-phosphate (TBP) extraction. Thereafter its radioactivity was determined by liquid scintillation counting (LSC) and its mass concentration by multi-collector inductively coupled plasma spectrometry (MC-ICP-MS). So a new value of Zr-93 half-life was found to he (1.13 +/- 0.11) x 10(6) a.
