Project IPAD, a database to catalogue the analysis of Fukushima Daiichi accident fragmental release material

For the full database, please visit: www.projectipad.org The 2011 accident at Japan’s Fukushima Daiichi Nuclear Power Plant released a considerable inventory of radioactive material into the local and global environments. While the vast majority of this contamination was in the form of gaseous and aerosol species, of which a large component was distributed out over the neighbouring Pacific Ocean (where is was subsequently deposited), a substantial portion of the radioactive release was in particulate form and was deposited across Fukushima Prefecture. To provide an underpinning understanding of the dynamics of this catastrophic accident, alongside assisting in the off-site remediation and eventual reactor decommissioning activities, the ‘International Particle Analysis Database’, or ‘IPAD’, was established to serve as an interactive repository for the continually expanding analysis dataset of the sub-mm ejecta particulate. In addition to a fully interrogatable database of analysis results for registered users (exploiting multiple search methods), the database also comprises an open-access front-end for members of the public to engage with the multi-national analysis activities by exploring a streamlined version of the data.如需获取完整数据库，请访问：www.projectipad.org 2011年日本福岛第一核电站事故向当地及全球环境释放了大量放射性物质。其中绝大多数污染物以气体和气溶胶形态存在，大量组分随后扩散至邻近太平洋并沉降于此，另有相当一部分放射性释放物以颗粒物形式存在，并沉降于福岛县境内。为深入理解这场灾难性事故的动力学机制，同时协助场外去污整治与最终的反应堆退役工作，国际颗粒物分析数据库（International Particle Analysis Database，简称IPAD）正式建立，作为亚毫米级喷射颗粒物持续扩充的分析数据集的交互式存储库。该数据库除面向注册用户提供可全面查询的分析结果数据库（支持多种检索方式）外，还设有开放访问前端，供社会公众通过探索精简版数据集，参与这项跨国分析活动。
