Radioactive substances in the air over Northern Europe (total gamma dose rate)

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 ambient gamma dose rate measurements collected by the EURDEP network during those days.
