Instead of conventional Ge semiconductor detectors and NaI(Tl) scintillation spectrometers, an application of a CdZnTe semiconductor (CZT) whose crystal has the dimension of 1 cm cubic to the in situ environmental radioactivity measurement was attempted in deeply affected areas in Fukushima region. Results of deposition density on soil for (134)Cs/(137)Cs obtained seemed consistent, comparing obtained results with those measured by the Japanese government.
在福岛地区受影响严重的区域，尝试将晶体尺寸为1立方厘米的碲锌镉半导体（CZT）应用于现场环境放射性测量，以替代传统的锗半导体探测器和碘化钠（铊）闪烁光谱仪。将获得的（134）铯/（137）铯在土壤上的沉积密度结果与日本政府测量的结果相比较，所得结果似乎是一致的。
