【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60Co γ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％。更多还原

【Abstract】 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 means of 6Li-7Li pair 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 interferenc is up to 18. 7% has been obtained.更多还原
