Kashiwa city, inside the Tokyo metropolitan area and located ~200 km south of the Fukushima Dai-ichi Nuclear Power Plant, received a raised environmental ambient radiation dose due to the disaster relative to the rest of area. In this paper, the challenging process of the official voluntary decontamination activity in Kashiwa city, Chiba prefecture, which was carried out with strong cooperation between a local government and experts, is described and reviewed in terms of the effectiveness of the radiation protection. The support system for the official voluntary decontamination work was constructed by the citizens. It was completed within ~15 months after the accident, by way of the following five main steps. (i) A local forum was organized, commencing an open discussion. (ii) (a) Some civic groups started their own activities independent of the national and local governments' policies and measures, and (b) Kashiwa city office held information symposia and risk communication meetings with key persons as a kind of stakeholders as well as education and training of official leaders for voluntary decontamination work. (iii) Joint positive discussion and work projects between civic groups and the local government were started by key personnel. (iv) Local government planned and fixed its official decontamination strategy based on the results of several open discussions. (v) A guidance book for official voluntary decontamination by citizens was distributed by Kashiwa city office. The systematic framework for voluntary decontamination by citizens in Kashiwa city was developed through cooperation between a local government and decontamination experts, which was rare at that time. The authors believe that the process is valuable and should be shared with experts from various fields around the world.
柏市位于东京都市区内，距离福岛第一核电站以南约200公里，由于这场灾难，其环境辐射剂量相对于该地区其他地方有所增加。本文描述并回顾了千叶县柏市官方自愿去污活动的艰难过程，该活动是在地方政府与专家的紧密合作下开展的，并从辐射防护的有效性方面进行了评估。官方自愿去污工作的支持系统由市民构建。事故发生后约15个月内，通过以下五个主要步骤完成。（i）组织了一个地方论坛，开始公开讨论。（ii）（a）一些民间团体独立于国家和地方政府的政策及措施开展自身活动，（b）柏市办公室与作为利益相关者的关键人物举行了信息研讨会和风险沟通会议，并对官方自愿去污工作的负责人进行了教育和培训。（iii）关键人员启动了民间团体与地方政府之间的积极联合讨论和工作项目。（iv）地方政府根据多次公开讨论的结果制定并确定了其官方去污策略。（v）柏市办公室分发了市民官方自愿去污指导手册。柏市市民自愿去污的系统框架是通过地方政府与去污专家的合作建立起来的，这在当时是很少见的。作者认为这个过程很有价值，应该与世界各地不同领域的专家分享。
