Much more: 'Brief Radiation Spike' Reported After Deadly Rocket-Engine Blast In RussiaRussia's Defense Ministry says two people were killed and six injured in an explosion and fire at a military unit in Russia's northwestern Arkhangelsk region.
The ministry said a fire broke out after a reaction engine exploded on August 8 "when testing a liquid propulsion system."
Regional authorities said that the explosion and fire took place near the town of Nyonoksa, where a navy ballistic missile test range for nuclear submarines is located.
There have been "no harmful chemicals released into the atmosphere," the Defense Ministry said, adding that "radiation levels are normal."
However, the nearby city of Severodvinsk said a "brief spike" in radiation levels was registered after the blast.
“Sensors in Severodvinsk recorded a short-term increase in radiation levels. Currently, the levels have returned to normal,” according to a statement on the city’s website, citing readings between 11:50 a.m. and 12:30 p.m. local time.
