Small amounts of radioactive iodine were detected in outdoor air in several European countries in January. An amount of iodine isotope 131 exceeding the detection limit was measured at least in Finland, Norway, Poland, the Czech Republic, Germany, France and Spain.

In Finland, the amount of iodine in the atmosphere was very small, but detectable in the samples collected at the air radioactivity monitoring stations in Rovaniemi and Kotka. The measurement results are available on the STUK website Radioactivity in outdoor air.

The situation was similar in other countries reporting iodine findings. The largest concentrations were measured in Poland, but even those were very far from concentrations that might have any effect on human health.

The origin of the iodine is unknown. Iodine 131 is commonly used for medical purposes to treat hyperthyroidism and thyroid cancer and is manufactured in a number of countries around the world.
