摘要
用ＨＰＧｅγ谱仪与低本底ＮａＩ（Ｔ１）γ谱仪相结合，通过测量放射性废水中￣（９０）Ｓｒ－￣（９０）Ｙ发射的高能电子与探测器作用所产生的韧致辐射，确定￣（９０）Ｓｒ含量。运用本方法取样测量了中国原子能科学研究院积存的７种放时性废水样品。５种废水中￣（９０）Ｓｒ含量的测量结果与放化法测量结果在１０％以内相符。
A direct wav is found to determine the content of ￣(90)Sr in radioactive waste waters. Witj thecombination of HPGe γ spcetrometer and low background NaI(T)γ spectrometer,the contents of￣(90)Sr in radioactive waste waters arising from CIAE are determined by measuring the intensity ofbremsstrahlung produced from￣(90)Sr-￣(90)Y. The measured results of five kinds of waste water areagreeable to those by radiochemical analvsis within 10 %.
