Radioactive iodine detected in northern Norway days after Russian blast
Norway’s nuclear safety authority said on Thursday it is analysing tiny amounts of radioactive iodine detected in the air in northern Norway days after a deadly explosion over the border in Russia.
Russia’s state nuclear agency Rosatom said on Saturday that five people killed in the blast were its staff members, and the accident involved “isotope power sources”, giving no further details.
The Norwegian radiation and nuclear safety authority DSA said it had spotted the radioactive iodine at its air filter station in Svanhovd, which is by the Russian border. A river separates the two countries.
The samples were collected in the period August 9-12, while the accident in the Arkhangelsk region of northern Russia occurred on August 8, it added.
“At present it is not possible to determine if the last iodine detection is linked to the accident in Arkhangelsk last week. DSA continues more frequent sampling and analysis,” DSA said.
Such radiation measurements are not unusual in Norway as its monitoring stations detect radioactive iodine about six to eight times a year and the source is usually unknown.
Russia’s state weather service Rosgidromet said on Tuesday that radiation levels in the city of Severodvinsk had spiked by up to 16 times last Thursday. Medics who treated victims of the accident have been sent to Moscow for a medical examination, the TASS news agency reported.
