Thursday, two people were killed in an explosion on a military base in northern Russia. Shortly after the explosion, a short peak of radioactive radiation was measured, writes the Russian news agency Tass . As a precaution, Russia has closed part of the White Sea for a month for shipping traffic.

It would be Dvina Bay, one of the four major areas within the White Sea. As a result, freight traffic can no longer reach the Russian port city of Arkhangelsk in the near future.

A rocket filled with liquid fuel exploded in the vicinity of the port city. Two rocket specialists were killed, while at least six other employees of the base and some civilians were injured.

The increased amount of radiation was measured in the vicinity of Severodvinsk, another port city on the White Sea. The cause of the peak is not yet clear. BBC News writes on the basis of conversations with residents that residents should take iodine pills there. In addition, children must stay indoors. About 200,000 people live in the city.

Moscow: No dangerous substances released

The Russian Ministry of Defense says in a reaction that a defect occurred during a test but that no hazardous substances were detected in the air. Nor would large amounts of radiation have been released.

It is the second incident on a military basis in Russia within one week. A weapon depot previously caught fire in eastern Siberia, followed by a series of explosions. Tens of thousands of people had to be evacuated. An area the size of Belgium would have been on fire.
