What is Microdosimetry for the characterization of the THOR epithermal neutron beam about?

The epithermal neutron beam of the Tsing Hua Open-pool Reactor (THOR) was constructed for the study of boron neutron capture therapy (BNCT). The THOR epithermal neutron beam was mainly composed of thermal neutrons, fast neutrons, and photons. For fast neutrons and photons, the absorbed dose and the relative biological effectiveness (RBE) were used to characterize radiation dose and radiation quality. The short-ranged alpha particles and lithium ions produced from 10 B(n,a) 7 Li reactions in the BNCT required cellular-and micro-dosimetry characterizations. Due to the non-uniform microdistribution of boron in cells, these characterizations should depend on the sourceetarget geometry. In this case, the geometrydependent specific cellular dose and lineal energy could be used to describe radiation dose and radiation quality. In the present work, cellular-and micro-dosimetry were studied for the THOR epithermal neutron beam. The specific cellular dose and lineal energy were calculated for thermal neutron-induced a-particles and 7 Li-ions with different sourceetarget geometry and various cell sizes. Applying the linear energy dependent-biological weighting function, the geometry-dependent
