Severodvinsk authorities positioned rescue providers on excessive alert as measurements instantly after the incident confirmed background radiation ranges thrice above the protected restrict of 0.6 microsieverts. In lower than half an hour, nonetheless, they dropped again to regular – and the each day common remained throughout the norms, thus posing little threat for the inhabitants, metropolis authorities mentioned.

“We are monitoring [the radiation levels] around the clock. Over the last 24 hours, no change was witnessed,”Severodvinsk’s metropolis administration mentioned Friday.
