Tests of a large volume Bismuth Germinate (BGO) detector were carried out to detect low energy prompt gamma-rays from boron and cadmium-contaminated water samples using a portable neutron generator-based Prompt Gamma Neutron Activation Analysis (PGNAA) setup. Inspite of strong interference between the sample- and the detector-associated prompt gamma-rays, an excellent agreement has been observed between the experimental and calculated yields of the prompt gamma-rays, indicating successful application of the large volume BGO detector in the PGNAA analysis of bulk samples using low energy prompt gamma-rays.
使用基于便携式中子发生器的瞬发伽马中子活化分析（PGNAA）装置，对大体积锗酸铋（BGO）探测器进行了测试，以探测硼和镉污染水样中的低能瞬发伽马射线。尽管样品相关和探测器相关的瞬发伽马射线之间存在强烈干扰，但在瞬发伽马射线的实验产额和计算产额之间仍观察到了极佳的一致性，这表明大体积BGO探测器成功应用于利用低能瞬发伽马射线对大量样品进行PGNAA分析。
