本文报道一台以φ75×75mm 的 NaI(Tl)晶体为主探测器,以φ430×500mm 的环型塑料闪烁体为反符合探测器,以另一φ75×75mm 的 NaI(Tl)晶体为符合探测器所组成的反符合屏蔽低本底γ谱仪。采用含放射性杂质少的结构物质和屏蔽材料,符合、反符合等措施降低本底。在井型反符合屏蔽条件下,主探测器在0.05—2.0MeV 能区内的积分本底为68cpm。对~(137)Cs(φ8mm)面源的能量分辨率为10.5%,全能峰效率为10.9%,康普顿散射减弱因子可达2.1;当测量时间为1000min,置信水平为95%时,面源最小可探测下限为1.13dpm。该谱仪适于环境样品及某些弱放射性样品的测量。
