This research reviews the performance of a commercial personal fast neutron dosimetry system that has recently been installed in the External Dosimetry Laboratory at Soreq Nuclear Research Center (SNRC). Different kinds of neutron sources like ${}{}^{\mathbf{241}}\boldsymbol{Am}$-Be, ${}{}^{\mathbf{252}}\boldsymbol{Cf}$ and some neutron generators are used in the industry as well as in some research institutes and reactors. The workers in these places need to be regularly monitored for neutron radiation. These workers' individual neutron doses have been estimated at SNRC until recently by a 30-year-old in-house-made system based on the CR-39 ® solid state nuclear track (SSNT) detector technology. Last year, a new Landauer CR-39 ® neutron dosimetry system was adopted, the Neutrak system. This system employs a standard etching technique using NaOH solution, and measures the SSNT dosimeters automatically and in a repeatable manner. This paper reviews the performance of Landauer's commercial personal neutron dosimetry system. The system performance shows excellent results in terms of linearity, repeatability, robustness, etch parameters sensitivity and detection threshold.

SNRC 新型个人中子剂量测量系统的性能研究。

本研究回顾了最近安装在 Soreq 核研究中心 (SNRC) 外部剂量学实验室的商用个人快中子剂量学系统的性能。不同种类的中子源，例如 ${}{}^{\mathbf{241}}\boldsymbol{Am}$-Be、${}{}^{\mathbf{252}}\boldsymbol{Cf}$ 和一些中子发电机用于工业以及一些研究机构和反应堆。这些地方的工人需要定期监测中子辐射。直到最近，SNRC 一直在估计这些工人的个人中子剂量，该系统有 30 年历史，内部制造的系统基于 CR-39 ® 固态核轨道 (SSNT) 探测器技术。去年，采用了一种新的 Landauer CR-39 ® 中子剂量测定系统，即 Neutrak 系统。该系统采用使用 NaOH 溶液的标准蚀刻技术，并以可重复的方式自动测量 SSNT 剂量计。本文回顾了 Landauer 的商用个人中子剂量测定系统的性能。系统性能在线性度、可重复性、稳健性、蚀刻参数灵敏度和检测阈值方面显示出出色的结果。
