摘要
介绍两路或多路NaI(Tl)探测器γ能谱数据的合成方法及初步成果,以"特征峰叠加"的方法对137Cs和60Co的仪器谱进行单峰和双峰的叠加试验,为天然γ能谱合成提供依据。实验表明,"特征峰叠加"的方法可较好地反映各仪器谱合成前的特性,有很好的应用前景。
This paper introduces synthesis methods and preliminary results of the two or more ways NaI (T1) detector γ-ray spectrum data. The superposition experiment of single peak and two peaks on instrument spectrum of 137^ Cs ^60 Co by means of characteristic peaks synthesis, which provides a basis of synthesis of natural γ-ray spectrum. The experiment shows that the synthesis method of the characteristic peaks can be better reflected on characteristics of the instrument spectrum before synthetic, and the method has good application prospect.
