Reverse-biased silicon p-n junction arrays have been proposed as microdosimetry detectors. The tissue equivalence of such detectors in boron neutron capture therapy (BNCT) is discussed. A comparison of the range-energy relationships of H, He, C, and Li ions in tissue (ICRU-muscle) and silicon is given. A simple geometrical scaling (approximately 0.63) of linear dimensions is required to convert microdosimetric energy deposition measurements performed in silicon to equivalent deposition in tissue. The Monte Carlo technique is used to examine energy deposition for two simple geometrical cases applicable to BNCT.
反向偏置的硅p-n结阵列已被提议作为微剂量学探测器。讨论了此类探测器在硼中子俘获疗法（BNCT）中的组织等效性。给出了H、He、C和Li离子在组织（ICRU肌肉）和硅中的射程-能量关系的比较。需要对线性尺寸进行简单的几何缩放（约为0.63），以便将在硅中进行的微剂量学能量沉积测量转换为在组织中的等效沉积。使用蒙特卡罗技术来研究适用于BNCT的两种简单几何情况下的能量沉积。
