A dosimetric technique based on proportional counter microdosimetry has been developed for the dosimetry of mixed radiation fields employed in boron neutron capture therapy (BNCT). The technique has been successfully used to measure the gamma, fast neutron and the boron dose rates in the mixed radiation field from a 252Cf source. The measured fast neutron and boron dose rates are in good agreement with the calculations and the measurements reported by other researchers. A systematic discrepancy is observed in the gamma dose rate measurements, with the present measurements being approximately 35% lower than those reported elsewhere.
已开发出一种基于正比计数器微剂量学的剂量测定技术，用于硼中子俘获疗法（BNCT）中使用的混合辐射场的剂量测定。该技术已成功用于测量来自252Cf源的混合辐射场中的γ射线、快中子和硼剂量率。测得的快中子和硼剂量率与其他研究人员的计算结果和测量值吻合良好。在γ剂量率测量中观察到一个系统性差异，目前的测量值比其他地方报道的值低约35%。
