Description

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±0.05) min and (10.35±0.04) min for 94Y and 95Y, respectively. (authors)
