The response in terms of personal dose equivalent of a passive fast neutron dosimeter composed of a CR-39 detector coupled with a $1$-cm-thick PMMA radiator is investigated in monochromatic neutron fields via simulations and experiments. In particular, the simulations were performed through the Monte Carlo FLUKA code (version 2011.2x.5), while the experimental fields were produced at the AMANDE facility (IRSN, France). The dosimeter response is studied with respect to both the energy and the angle of incidence of the radiation field on the device. The simulated response shows a quite stationary trend, that is, minimal variation across a wide energy range, also for different irradiation angles. The agreement between simulated and experimental responses indicates the simple and cheap dosimeter presented as promising for personal dosimetry applications in practical situations.

无源快中子剂量计的个人剂量当量响应，由CR-39探测器与$1$通过模拟和实验在单色中子场中研究了-cm 厚的PMMA辐射器。特别是，模拟是通过蒙特卡罗FLUKA代码（版本 2011.2x.5）进行的，而实验场是在AMANDE设施（IRSN， 法国）。剂量计响应是根据辐射场在设备上的能量和入射角来研究的。模拟响应显示了一个非常稳定的趋势，即在很宽的能量范围内变化很小，对于不同的照射角度也是如此。模拟和实验响应之间的一致性表明，这种简单且廉价的剂量计在实际情况下对个人剂量测定应用很有希望。
