The performance of a new Compton-suppression spectrometer consisting of one HPGe detector and three NaI(Tl) detectors was studied. The peak-to-Compton ratio for a (137)Cs source is 1150 and the integral background count rate is 0.3 5s(-1) over the energy interval 20-3000 keV. The spectrometer was used to acquire both Compton-suppressed and non-suppressed spectra of aerosol samples collected in Beijing following the Fukushima nuclear accident.
研究了一种由一个高纯锗探测器和三个碘化钠（铊）探测器组成的新型康普顿抑制谱仪的性能。对于一个铯-137源，峰康比为1150，在20 - 3000 keV能量区间的积分本底计数率为0.3次/5秒。该谱仪用于获取福岛核事故后在北京采集的气溶胶样品的康普顿抑制谱和非抑制谱。
