摘要

2011年3月发生在东京电力公司（TEPCO）福岛第一核电站（Fukushima Daiichi Nuclear Power Plant）的事故加剧了许多市民对辐射暴露的担忧。因此，开发了一种剂量计，使任何人都能轻松测量辐射暴露，供居民在发生核事故时使用（D-Shuttle；千代田技术公司，日本东京）。D-Shuttle被广泛使用，主要在福岛县；然而，用户对其基本性能的评价却很少。本文研究了d型梭的基本性能，包括测量值的稳定性。结果发现，多个D-Shuttle单元之间的灵敏度以及更换电池前后的测量值没有显著差异。这表明了d -梭测量的稳定性。由于无法检测α射线和β射线，D-Shuttle只能用于γ射线测量。D-Shuttle后侧面的测量值是前侧面测量值的66.7%。这表明D-Shuttle在背面的敏感度较低。

Performance evaluation of personal dosimeter D-Shuttle for use by residents in the event of a nuclear accident

The accident at the Tokyo Electric Power Company's (TEPCO's) Fukushima Daiichi Nuclear Power Plant in March 2011 elevated the concerns of many citizens regarding radiation exposure. Therefore, a dosimeter that enables anyone to easily measure radiation exposure was developed for use by residents in the event of a nuclear accident (D-Shuttle; Chiyoda Technol Co., Tokyo, Japan). The D-Shuttle is widely used, mainly in the Fukushima Prefecture; however, there are few user evaluations on its basic performance.

This paper investigates the basic performance of the D-Shuttle, including the stability of the measured values. It was found that there was no significant sensitivity difference among the multiple D-Shuttle units or in the measured values before and after battery replacement. This indicates the stability of D-Shuttle measurements. As α- and β-rays could not be detected, D-Shuttle should only be used for γ-ray measurements. The measured value on the back side of the D-Shuttle was 66.7 % of that on the front side. This indicates that the D-Shuttle is less sensitive on the back side.

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
