What is the role of experts and their expertise in the context of trans-science, in which issues that are raised in scientific terms cannot be answered by science alone? This article examines the discourses and practices around safety of low-dose exposure to radiation in the ongoing aftermath of the Fukushima Daiichi Nuclear Power Plant accident in Japan in 2011. Following the nuclear fallout, scientific experts and STS scholars in Japan debated what forms of science communication were adequate to address the situation. Ethnographic research and textual analysis of their debates show a shift in emphasis on the role of experts from cultivating ‘public understanding of science’ for the sake of science and policy to an ‘expert understanding of the public’ for the sake of the public and its diverse everyday concerns. Two forms of expertise are emerging: ‘co-expertise’ and ‘intra-mediary expertise’. Both are parts of a transition from a paternalistic form of expertise to one that acknowledges the need to engage the public to address issues of scientific uncertainty. However, co-expertise ultimately upholds the existing political structures that shape risk governance, while intra-mediary expertise engages those often excluded from current structures of accountability. Discussion of the potentials and limitations of emerging forms of expertise in Japan show that epistemic justice is not enough. Civic justice that acknowledges diverse publics and their needs must be upheld in the uncertain sphere between science, politics, and everyday life.

媒体内专业知识：跨科学和专家对公众的理解

在跨科学背景下，专家及其专业知识的作用是什么？在跨科学背景下，用科学术语提出的问题无法仅靠科学来回答？本文探讨了 2011 年日本福岛第一核电站事故发生后，围绕低剂量辐射安全的讨论和实践。核事故发生后，日本的科学专家和 STS 学者就什么形式的科学展开了争论沟通足以解决这种情况。民族志研究和对他们辩论的文本分析表明，对专家作用的重视已经从为了科学和政策而培养“公众对科学的理解”转变为为了公众及其利益而培养“公众对科学的专家理解”。各种日常问题。两种形式的专业知识正在出现：“共同专业知识”和“中介专业知识”。两者都是从家长式的专业知识向承认需要让公众参与解决科学不确定性问题的专业知识转变的一部分。然而，共同专业知识最终维护了塑造风险治理的现有政治结构，而内部专业知识则吸引了那些经常被排除在当前问责结构之外的人。对日本新兴专业知识形式的潜力和局限性的讨论表明，认知正义是不够的。承认不同公众及其需求的公民正义必须在科学、政治和日常生活之间的不确定领域得到维护。
