This paper describes the calibration of the efficiency for a Ce(Li) anti-Compton detector system with anticoincidence Nal(T1) annulus.An absolute efficiency curve for 80-2000 keV γ-ray has been determined.The central detector used is an end-closed coaxial Ge(Li) detector about 165 cm9,and the shielding detector consists of a Nal(Tl) annulus about 0250x250 mm and a Nal(T1) back plug detector about 76×76 mm.The calibration source is a mixture of 152Eu+132Ta and soil,which is about 75×22 mm in size...

This paper describes the calibration of the efficiency for a Ce(Li) anti-Compton detector system with anticoincidence Nal(T1) annulus.An absolute efficiency curve for 80-2000 keV γ-ray has been determined.The central detector used is an end-closed coaxial Ge(Li) detector about 165 cm9,and the shielding detector consists of a Nal(Tl) annulus about 0250x250 mm and a Nal(T1) back plug detector about 76×76 mm.The calibration source is a mixture of 152Eu+132Ta and soil,which is about 75×22 mm in size and with a weight of 100 g.The choice for the calibration peaks and the expression of the function fitted with the peak efficiency data are discussed.The results have been checked with the reference standard material for environment radioactivity provided by NBS,USA.

对用NaI(Tl)作反符合屏蔽的Ge(Li)反康普顿探测系统的效率进行了刻度。Ge(Li)主探测器为一个约165cm~3的闭端同轴探测器,屏蔽探测器为φ250×250mm的NaI(Tl)环和φ76×76mm的后塞探测器。γ射线能量为(80~2000)keV,标准源为φ75×22mm、重约100g、土壤介质的体源。探讨了刻度峰的选择和峰面积效率曲线的函数表达式。用NBS提供的环境放射性标准参考物质进行了检验。

For the purpose of preparing the guard counting of anti-compton γ-spectrometer,a large,volume PSTP—TP(2%)POPOP(0.02%)plastic—scintillator is made by ourselves,its dimensions are Φ520mmx500mm.In this work some charactesistics of this plastic scintillator have beenevaluated.They have shown that it can be favourably compared withmost of small commercially available plastic scintillators.

为了用作反康普顿谱仪的屏蔽环,需要大体积的塑料闪烁体,因此试制成了直径为500毫米,高为520毫米的苯乙烯—对三联苯(2%)——POPOP(0.02%)塑料闪烁体.在本工作中测量了这个塑料闪烁体的一些性能.从其性能可知,它可以和大部分商品生产的小塑料闪烁体相比.
