| 摘 要： | 用自行研制的IRM80S-TE1和IRM81T-TE1两种组织等效电离室与用Mullard G-M计数管组装的γ剂量计,组成双探测器,建立了裂变中子-γ混合场比释动能测定方法。测量结果总的估计不确定度为±5.2％。并与用美国FWT IC-17A组织等效电离室所测得的数据进行了比较,三种电离室在裂变中子场中的总响应及中子比释动能的测量结果在±0.4％之内符合。本文所用的测量方法对其它快中子场测量也是适用的。

| Abstract: | The two-detectors method was applied to the measurement of tissue kerma in reactor fission mixed neutron-photon field. The hydrogenous detector employed was of two types, the spherical type IRM80S-TE1 and thimble type IRMSIT-TE1 tissue equivalent ionization chambers, both developed by us and the non-hydrogenous detector was the neutron insensitive Mullard MX 151 Geiger-Mueller counter. The results of measurement with IRM80S-TE1 and IRM81T-TE1 ionization chambers were found to be in good agreement with values obtained by the FWT IC-17A ionization chamber. |
