In this detection system, the protective ring and grill normally included in the PAS-8 when same is used as a free probe, is deleted to enhance sensitivity to alpha radiation. The STB-3 Beta-Gamma GM System substitutes a modified P-11 Pancake probe for the alpha scintillation detector. It also deletes the protective aluminum grill normally included in the probe to increase sensitivity to low energy Betas. 型号 STAM-2α 闪烁系统结合了改进后的 PAS-8α 闪烁探头,加TM-2 探头座和抽屉取样系统.在这个 探测系统中,正常安装在 PAS-8 保护圈和格栅被拆除以增加 α 辐射灵敏度.STB-3β-γGM 系统用改进后 的P-11 扁平探头替换了 α 闪烁探头,并拆除了正常安装在探头内的保护铝格栅以增加低能 β 灵敏度.

5 MeV Alphas is typically 80-85% of

2 pi. It is completely insensitive to Betas and Gammas. Background is typically less than one count per minute. The sensitivity of the STB-3 to Betas of energy

60 KeV and up ranges from 30% to 100% of

2 pi depending on energy of beta and backing material. Background is typically 30-50 counts/minute. Sample cavity is 2-1/16'' diameter x 3/8'' deep. STAM-2 对于
