| 中文摘要 | 用脉冲反应堆热中子辐照浓缩235U溶液靶,经快速放射化学分离纯化出94Y和95Y溶液,稀释并制备放射性浓度依次相差～10倍的3个测量源。将测量源放置在井式HPGe探测器井内,采用质量归一法测得94Y和95Y的半衰期分别为(19.16±0.05)min和(10.36±0.03)min。; Solutions of enriched 235U were irradiated in thermal-neutron flux produced by a pulsed reactor,and 94Y and 95Y were separated chemically from the fission products immediately. The purified solution of 94Y and 95Y is diluted about ten times in sequence to three concentration solutions. Three sources were prepared with the solutions. The sources are measured,from the lower concentration to higher one,with a well-type HPGe detector to determine the half-life of 94Y and 95Y. The determined half-life results are (19.16�05) min and (10.35�04) min for94Y and 95Y,respectively. |
