能量响应标定中的单能γ获取技术

The technique of obtaining single-energy γ-rays in calibrating energy response of detector

简要叙述了将强60Co辐射源转换为系列单能γ辐射源的原理和方法,重点介绍了两个关键技术:辐射屏蔽技术和降低能量弥散技术,研制出了一个有效的实验装置,使信噪比达到了10:1、能量弥散度达到了6%以下。

This paper introduces the principle of transforming γ-rays from 60Co into a series of single-energy γ-rays and stresses the technique of shielding radiation-interfere and reducing energy-dispersion. The single-energy γ-rays of any energy in the range of 0. 36-1. 02MeV may be obtained by means of this technique.
