Energy distributions of secondary charged particles were calculated in tissue substitutes irradiated by neutrons from 0.14 to 65 MeV, using the Particle and Heavy Ion Transport code System. The calculations were compared with experimental data measured by tissue equivalent proportional counters (TEPC). It is found that the calculated distributions of the lineal energy, y, generally agree well with the measured ones for neutrons from several 100 keV to 15 MeV. In the case of 40 and 65 MeV neutron irradiations, wall effects of TEPC should be considered and the fluence of alphas is underestimated by the calculations. Integrated dose contributions of the secondary charged particles are generally in good agreement with those of the measured ones.
使用粒子与重离子传输代码系统，计算了能量范围为0.14至65 MeV的中子辐照组织等效物中次级带电粒子的能量分布。将计算结果与用组织等效正比计数器（TEPC）测量的实验数据进行了比较。结果发现，对于能量从几百keV到15 MeV的中子，计算得到的线能量y分布与测量值总体上吻合良好。在40 MeV和65 MeV中子辐照的情况下，应考虑TEPC的壁效应，并且计算低估了α粒子的注量。次级带电粒子的积分剂量贡献总体上与测量值吻合良好。
