An explosion rocked a secretive Russian nuclear test site inside the Arctic Circle last week. At first, Russian officials denied that the blast produced any radioactive activity. They also denied any evacuations would be needed.
But then authorities in a village near the explosion advised locals to vacate the town for several hours on Wednesday. Greenpeace reported that background levels of radiation in the area had spiked to 20 times normal levels. And the explosion killed at least five people, with Russia’s state atomic energy corporation finally admitting it occurred at a small nuclear reactor.
