Neutron spectra at various locations in a phantom, irradiated by collimated beams of 14 MeV neutrons and neutrons from 252 Cf and Po-Be sources, were calculated using the Monte Carlo technique. These spectra give an indication of the distortion in source spectra associated with neutron irradiations of the body for therapeutic and diagnostic purposes. The effect of the spectral distortions on the dose response of several activation and damage track detectors was investigated. Of the dosemeters studied, Np has a dose response most nearly independent (+/-10%) of the spectral changes.
使用蒙特卡罗技术计算了由14兆电子伏中子以及来自252锎和钋 - 铍源的中子的准直束照射的人体模型中不同位置的中子能谱。这些能谱表明了与用于治疗和诊断目的的人体中子照射相关的源能谱畸变情况。研究了能谱畸变对几种活化探测器和损伤径迹探测器剂量响应的影响。在所研究的剂量计中，镎的剂量响应几乎与能谱变化无关（±10%）。
