166Hom是一种长寿命放射性核素,半衰期为(1200±200)a,它放出约40条γ射线,能量为80～1450keV,可用于高分辨率半导体探测器的能量和效率刻度。准确测量166Hom的活度,可以为高气压4πγ标准电离室和高纯锗γ谱仪等标准装置提供良好的长期稳定性监督源。为此,国防科工委放射性计
The 166Hom is a long-lived radionuclide with a half-life of (1200 ± 200) a. It emits about 40 gamma rays and has an energy of 80 to 1450 keV. It can be used for energy and efficiency calibration of high resolution semiconductor detectors. The accurate measurement of 166Hom activity provides a good source of long-term stability monitoring for standard devices such as high pressure 4πγ standard ionization chambers and high purity germanium gamma spectrometers. To this end, the National Defense Commission radioactive
