Russian officials said Wednesday that although the explosion in a vat of atomic waste at a secret Siberian complex could be considered the country's worst nuclear accident since Chernobyl, it was tiny in comparison. "You simply cannot liken it to Chernobyl," Nuclear Energy Ministry spokesman Georgy Kaurov told reporters. "About 80 million curies of radioactivity were released at Chernobyl. Here, we do not have even a single curie. So it is 80 million times less."
