The Norwegian Radiation and Nuclear Safety Authority (DSA) has recorded an increase in radiation levels at the border with Russia. Traces of cesium-137 have been detected, The Barents Observer informs.

The radioactivity was measured in filters at Viksjøfjell and Svanhovd in the second week of September, but the origin is still unknown. Norwegian Radiation and Nuclear Safety Authority (DSA) says the amount of Cesium discovered in the air filters is “very low.

The Norwegian Radiation and Nuclear Safety Authority announced Tuesday that it had recorded elevated levels of radioactive caesium along the country’s border with Russia. Veuer’s Matt Hoffman reports.

One fear is that the radiation traces could relate to Russia's Pankovo test site for the Burevestnik - a nuclear-powered cruise missile - on the Novaya Zemlya archipelago.
