The majority of the area contaminated by the Fukushima Daiichi Nuclear Power Plant accident is covered with forests. We developed a dataset for radiocaesium (Cs) in trees, soil, and mushrooms measured at numerous forest sites. The Cs activity concentration and inventory data reported in scientific journal papers written in English and Japanese, governmental reports, and governmental monitoring data on the web were collated. The ancillary information describing the forest stands were also collated, and further environmental information (e.g. climate) was derived from the other databases using longitude and latitude coordinates of the sampling locations. The database contains 8593, 4105, and 3189 entries of activity concentration data for trees, soil, and mushrooms, and 471 and 3521 entries of inventory data for trees and soil, respectively, which were collected from 2011 to 2017, and covers the entire Fukushima prefecture. The data can be used to document and understand the spatio-temporal dynamics of radiocaesium in the affected region and to aid the development and validation of models of radiocaesium dynamics in contaminated forests.
福岛第一核电站事故污染区域的大部分地区都被森林覆盖。我们开发了一个数据集，用于测量众多森林地点的树木、土壤和蘑菇中的放射性铯 (Cs)。我们整理了发表在英文和日文科学期刊论文、政府报告以及政府网站上的监测数据中报告的 Cs 活度浓度和清单数据。还整理了描述林分的辅助信息，并使用采样地点的经纬度坐标从其他数据库中进一步获取环境信息（例如气候）。该数据库包含 2011 年至 2017 年间采集的树木、土壤和蘑菇中活度浓度数据的 8593、4105 和 3189 条记录，以及树木和土壤中清单数据的 471 和 3521 条记录，涵盖了整个福岛县。这些数据可用于记录和了解受影响地区放射性铯的时空动态，并有助于开发和验证受污染森林中放射性铯动态的模型。
