Radioactive substances in the air over Northern Europe (air concentration samples)

In the first half of June 2020, small amounts of artificial (man-made) radioactive substances have been detected at several measuring stations in Northern Europe. Iodine-131 was detected in Norway, while cesium-134, cesium-137, cobalt-60 and ruthenium-103 were detected in Sweden and Finland. The amount of radioactivity was very low and there was no impact on the environment or human health. This dataset reports the air concentration samples measurements collected by the EURDEP network during those days.2020年6月上旬，北欧多个监测站点检出微量人工（人造）放射性物质。其中挪威境内检测到碘-131，瑞典与芬兰境内则检出铯-134、铯-137、钴-60及钌-103。本次检出的放射性活度水平极低，未对环境与人体健康造成任何影响。本数据集收录了欧洲放射性监测网络（EURDEP）在此期间采集的空气浓度样本实测数据。
