Arctic Radiation Levels From Chernobyl Declining

jangobongo writes "Nearly 20 years after the Chernobyl meltdown and much longer since Soviet nuclear weapons testing, radiation levels in the Arctic landmasses are finally declining. But nuclear disaster is still lurking on the horizon. The Kola Peninsula in northwest Russia is home to Russia's aging, decomissioned (and sinking) nuclear sub fleet as well as a depots of nuclear weapons and an old nuclear power plant. Estimated cost of clean up to prevent further toxic leakage is millions of euros."
