The Norwegian Radiation and Nuclear Safety Authority (DSA) has observed a rise in radiation levels along the border with Russia, with traces of cesium-137 detected.

Cesium-137 was detected at two radiation monitoring stations—Viksjøfjell and Svanhovd, Caliber.Az reports, citing The Barents Observer.

This radioactive isotope is produced by the decay of uranium-235, which is commonly used in nuclear reactor fuel and nuclear weapons.

Although the DSA states that the detected cesium levels were “very low,” they did surpass typical readings—approximately 5 microbecquerels per cubic meter.

It was highlighted that the cesium-137 traces were only found between September 9 and 12 at stations close to the Norway-Russia border, while other monitoring stations in northern Norway and Lapland did not report elevated radiation levels. Furthermore, no cesium-137 presence has been reported within Russia.
