In the air above the Netherlands is no radioactive iodine-131 measured, reports the national Institute for public Health and the Environment (RIVM). In Norway, Finland, Poland, the Czech republic, Germany, France and Spain last month, however, small amounts of the substance measured.
Where the iodine comes from is unknown. On the internet rumors that it would come from an accident in a nuclear reactor or even a test with a nuclear weapon. But that is according to the RIVM excluded. There would then not only iodine-131 release, but also other radioactive jodiumsoorten, such as cesium-137.
The iodine-131 is a man-made radioactive substance. For example, it is used in the treatment of thyroid cancer. The values reported are very low, from 0.1 to 5 microbequerel per cubic meter. Naturally there are various radioactive substances in air in the Netherlands, such as lead-210 and beryllium-7.
