采用BH1324多道及BH1220智能定标器等设备测量了2种型号的镍合金和铅对不同能量γ射线的吸收系数。实验结果表明,镍合金对γ射线的质量吸收系数随能量的增加减少较缓慢,在能量较高的区域质量吸收系数与铅的相近,因此可用镍合金作为γ射线的屏蔽材料。

The absorption coefficients of different energy gamma-ray on the two types of nickel alloy and lead are measured by BH1324 and BH1220 devices. The experimental results show that the mass-absorption coefficient of nickel alloy decreases slowly with the increase of gamma-ray energy, and the values are close to these of lead in the higher energy region. So nickel alloys are suitable to repla...
