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.

2011年，日本福岛第一核电站事故导致大量放射性物质释放至局部及全球环境。尽管其中大部分污染以气态和气溶胶形式存在，其中大量成分被散布至邻近的太平洋（随后沉积其中），但仍有相当一部分放射性释放以颗粒形式存在，并在福岛县境内沉降。为深入理解此次灾难性事故的动态，并协助现场修复以及最终的反应堆退役活动，成立了‘国际颗粒分析数据库’，简称‘IPAD’，作为不断增长的亚毫米喷射颗粒分析数据集的互动式存储库。数据库不仅为注册用户提供全面可查询的分析结果数据库（利用多种搜索方法），还包含一个面向公众的开放访问前端，使公众能够通过探索数据的简化版本，参与到跨国分析活动中。
