【摘要】 文中测得 Fe⁺³摩尔消光系数ε（25℃）/(Fe⁺³)=2181.5±12.0,对影响 FeSO₄剂量计的主要因素进行研究,准确性、重复性,响应线性较好。在3×10⁴Ci 辐照场测量,适应剂量范围28—440Gy。总不确定度<±3.0%。更多还原

【Abstract】 Determination of molecular optical density number of Fe⁺³（2181.5±2.0） was studied,major factors effecting ferrous sulfate dosimeter was also stu- died.The achieved accuracy,reproducibility and linear-response are quite good. The results measured under 3×10⁴ Ci of ⁶⁰Co γ-ray showed that it was suitable for measuring dosage from 28 to 440 Gy.更多还原
