Russia Confirms Radioactive Materials were Involved in Deadly Blast

摘要

A mystery explosion at a Russian weapons testing range involved radioactive materials, the authorities admitted, as the blast's admitted death toll rose and signs of a creeping radiation emergency, or at the least fear of one, grew harder to mask. In a statement released at 1 a.m. Saturday, Russia's nuclear energy company, Rosatom, said five employees had died, in addition to the two military personnel previously confirmed dead, as a result of a test involving "isotopic sources of fuel on a liquid propulsion unit."
