The characteristics and performances of the NIST High-Purity Germanium (HPGe), Sodium Iodide (NaI(Tl)) and Cadmium Telluride (CdTe) gamma-ray detectors were studied. The efficiencies, the minimum detectable activities and the energy resolutions of each were measured and compared. The data were analyzed using different software packages. The measurements were performed in a low background radiation environment using calibrated point sources. The CdTe detector showed a higher energy resolution than the NaI(Tl) detector but a lower efficiency than both the HPGe and NaI(Tl) detectors. This makes it a suitable detector only for relatively high activity measurements restricted to the 35 keV to 200 keV energy range.
对美国国家标准与技术研究院（NIST）的高纯锗（HPGe）、碘化钠（NaI(Tl)）和碲化镉（CdTe）γ射线探测器的特性和性能进行了研究。测量并比较了每种探测器的效率、最小可探测活度和能量分辨率。使用不同的软件包对数据进行了分析。测量是在低本底辐射环境中使用校准过的点源进行的。碲化镉探测器的能量分辨率高于碘化钠（NaI(Tl)）探测器，但效率低于高纯锗探测器和碘化钠（NaI(Tl)）探测器。这使得它仅适用于能量范围限制在35keV至200keV的相对高活度测量。
