“It must be borne in mind that the transfer of data from stations of the national segment of the international monitoring system for any country is purely voluntary,” Ryabkov told Interfax.

Thus, he commented on statements by representatives of the Organization of the Comprehensive Nuclear Test Ban Treaty (CTBTO) that Russia had stopped transmitting data from several nuclear test monitoring stations.

Ryabkov also noted that the interim technical secretariat (PTS) of the CTBTO Preparatory Commission (PC), which coordinates this work, "has in its mandate only and exclusively topics related to the Comprehensive Test Ban Treaty (CTBT)."

“National moratoriums imposed by nuclear powers are also adjacent here,” the deputy minister said.

He emphasized that the incident in the Arkhangelsk region “should not have any relation to the activities of the MTC PKB CTB.”

Ryabkov noted that the state of emergency at the training ground "does not bear any environmental risks, or any other risks for the environment, the population."

On August 8, five Rosatom employees died as a result of an emergency at a military training ground in the Arkhangelsk region. According to the corporation, tests of a rocket that exploded at a training ground took place in the White Sea. As noted, after the rocket explosion at the training ground, several Rosatom employees were thrown into the sea. The search continued until there was hope to find survivors.

As the state corporation’s press service added, the specialists of Rosatom who died during an emergency at a military training ground were aware of the potential danger of the work.

The Northern Administration for Hydrometeorology and Environmental Monitoring reported that on August 8 during the emergency at the landfill, the radiation level in Severodvinsk was 4-16 times exceeded.

Roshydromet said that the passage of a cloud of radioactive gases could be the cause of a short-term increase in the power of the ambient dose equivalent of gamma radiation (MAED) on August 8.
