Ge(Li)γ谱仪是一种先进的监测手段,由于分辨率高,一次测量可同时给出除~3H、~(90)Sr外,几乎所有的γ放射性核素的浓度。可以在事故情况下,完成大量的、时间性较强的、用其它分析方法无法胜任的分析任务,及时给出公众剂量估计,因而受到世界各国的重视。饮水、牛奶、尿等液体样品是放射性核素生物链转移中重要组成部分,在核事故的
Ge (Li) γ spectrometer is an advanced monitoring method. Due to its high resolution, a single measurement can simultaneously give almost all concentrations of γ-radionuclides other than ~ 3H and ~ (90) Sr. In the case of an accident, a large number of time-consuming analytical tasks that can not be performed by other analytical methods are completed and public dose estimates are timely provided, which is valued by all countries in the world. Liquid samples such as drinking water, milk and urine are important components of radionuclide biological chain transfer. In the case of nuclear accident
