本文叙述了用自己研制的组织等效电离室和组装的G-М计数管γ剂量计测定快中子比释动能的方法和测量结果,测量结果总的估计不确定度为±5.2%。并与用美国FWT IC-17A组织等效电离室和FWT GM-2计数管所测的结果进行了比对,两者符合得很好。
The two detector method was applied for kerma measurements in 15 MeV D-T mixed neutron-photon field. The hydrogenous detector employed is the thimble- type IRM 81-TE1 tissue equivalent ion chamber developed by us and the non-hydrogenous detector is the neutron-insensitive philips 18509 Geiger-Mueller counter. This paper describes the experimental devices
methods and measurement results. The results of IRM 81T-TE1 ion chamber are found to be in good agreement with values obtained by the FWT IC-17A ion chamber.
