摘要
本文讨论了将硫酸亚铁剂量计和铜－铁剂量计用于强脉冲混合辐射场测定的实验设计，利用直径２２０毫米的聚乙烯球，将硫酸亚铁剂量计的快中子响应降低到２０％以下，由它和完全暴露在中子、γ混合场中的硫酸亚铁剂量计响应之差，测量中子吸收剂量。这种方法两次实际用于强脉冲混合辐射场中子、γ吸收剂量测量，得到的结果和热释光剂量计、固体径迹探测器的测量结果进行了比较。
The application of iron sulfate and copper-iron dosimeters to experimental
design for measurements of high level pulse radiation field has been discussedThe
neutron absorbing dose could be measured by the difference of fast neutron response
of iron sulfate dosimeter between it exposes to the neutron and mixed field and to the
polyethylene bulb which diameter is 220mmThe fast neutron response could decrease
by 20% in the polyethylene bulbThe method has been twice applied to the measurement
of neutron and absorbing dose in the mixed radiation fieldComparison with the
experimental results of thermoluminescence dosimeter and solid track detector they are
agreement in the range of deviation 25%
