摘要
本文介绍了FJ422型BGO反康普顿屏蔽探测器的主要性能,它与ORTEC的高纯锗探测器相配合,在无物质屏蔽的条件下,对^(60)Coγ源在50—1100keV范围内的康普顿减弱系数为4—5.5,与同样效果的NaI(T1)屏蔽探测器相比较,其体积减小了80％。
In this paper the Anti-Compton Shield Detector of model FJ 422 is introduced. Being used with the ORTEC's HPGe detectors, in the absence of shield, it gives a suppression coefficient of 4.5 to 5.5 in the energy region of 50 to 1100 keV for 60Co. The total absorption coefficient of the BGO is compared to that of NaI(T1), but its volume decreases by 80%.
