Abstract The work presents a self-consistent algorithm to study the response of passive neutron dosimeters based on CR-39 detectors, through simulations with the FLUKA code (version 2011.2x.5). The various assumptions and features of the algorithm are described and the simulated results are compared to some experimental data referred to monochromatic and quasi-monochromatic neutron fields to show the potentialities and the limits of the procedure. Moreover, the response function of the dosimeter for normally impinging neutron fields is shown. In general, the algorithm turns out to work properly in estimating the dosimeter response, thus allowing to characterize the device in various situations in the frame of possible applications as an environmental and/or personal dosimeter.

基于CR-39径迹探测器的快中子场被动剂量计响应研究的自洽FLUKA算法

摘要 本文通过使用 FLUKA 代码（版本 2011.2x.5）进行仿真，提出了一种自洽算法来研究基于 CR-39 探测器的被动中子剂量计的响应。描述了该算法的各种假设和特征，并将模拟结果与一些涉及单色和准单色中子场的实验数据进行比较，以显示该过程的潜力和局限性。此外，还显示了剂量计对正常撞击中子场的响应函数。一般而言，该算法在估计剂量计响应时可以正常工作，从而允许在可能的应用框架内将设备表征为环境和/或个人剂量计的各种情况。
