The dual ionisation chamber technique is the recommended method for mixed field dosimetry of epithermal neutron beams. This paper presents initial data from an ongoing inter-comparison study involving two identical pairs of ionisation chambers used at the BNCT facilities of Petten, NL and of the University of Birmingham, UK. The goal of this study is to evaluate the photon, thermal neutron and epithermal neutron responses of both pairs of TE(TE) (Exradin T2 type) and Mg(Ar) (Exradin M2 type) ionisation chambers in similar experimental conditions. At this stage, the work has been completed for the M2 type chambers and is intended to be completed for the T2 type chambers in the near future.
双电离室技术是超热中子束混合场剂量测定的推荐方法。本文展示了一项正在进行的比对研究的初步数据,该研究涉及荷兰佩滕和英国伯明翰大学的BNCT设施所使用的两对相同的电离室。本研究的目的是在相似的实验条件下评估两对TE(TE)(Exradin T2型)和Mg(Ar)(Exradin M2型)电离室对光子、热中子和超热中子的响应。在现阶段,M2型电离室的工作已经完成,T2型电离室的工作预计在不久的将来完成。
