【摘要】 采用Na(Tl)闪烁谱仪用两种方法测量了平均能量为1.25MeV的60Co的γ射线在石蜡样品中发生康普顿散射的散射系数。在完全相同的实验条件下,利用此散射系数标定石蜡模拟油垢厚度,其结果最好一组平均相对误差在1.29%左右。更多还原

【Abstract】 1.25 MeV γ-ray of 60Co Compton scattering coefficient in the simple of paraffin,are measured by γ-ray energy spectrum analysis in two determining means.At the same experimental condition,we have used this scattering coefficient to determining grease thickness simulated by paraffin.The result show the average relative difference is about 1.29﹪ for the best group.更多还原
