摘要
依据６Ｌｉ玻璃闪烁体对中子、γ皆灵敏，而７Ｌｉ玻璃闪烁体仅对γ灵敏的特性，研究成功用６Ｌｉ、７Ｌｉ双玻璃闪烁体γ补偿法，实现在强γ辐射场干扰下，对弱中子注量率探测的方法。当６０Ｃｏγ在中子信号幅度区的干扰计数率，占中子计数率的１８．７％时，该方法对净中子注量测量结果导致的误差约为１％。
Based on the caracteristics of 6Li glass scintillator which is sensitive to both neutron and gamma rays, and 7Li glass scintillator which is sensitive to gamma rays only, a new method of detecting weak neutron flux under interference of strong gamma radiation has been investigated by mans of 6Li 7Li dual glass scintillator gamma compensation method. The result of neutron flux measurement by above mentioned method with an error of about 1% when the gamma ray interferenec is up to 18 7% has been obtained. (
