The Secret Effort To Clean Up a Former Soviet Nuclear Test Site

Lasrick writes "The Plutonium Mountain report has just been released by the Belfer Center at Harvard. It describes the remarkable effort the U.S. made to get the Russians to recognize the nuclear proliferation risk they left behind at the Semipalatinsk Nuclear Test when the Soviet Union collapsed. In this interview with Siegfried Hecker, he describes how he and other scientists at the Los Alamos National Laboratory recognized the risk to world security as the Semipalatinsk site became overrun with metal scavengers. Quoting: 'The copper cable thieves were not nomads on camelback, but instead they employed industrial excavation machinery and left kilometers of deep trenches digging out everything they could sell. We were concerned that some of that copper cabling could lead to plutonium residues.'"

Yes and No. It is a high alpha emitter, but that is low-energy and blocked by a piece of paper. It's not a big beta or gamma producer. The problem is more the poisonous effects and internal deposition....as alpha can make it through several nearby cells easily. This notion of spreading it out is rather ludicrous. Even if you could collect it all up (think big mining operations that produce massive amounts of waste itself) and then tried to spread it...it's a heavy metal and likes to clump. Unless you suddenly have hundreds of billions of dollars in your pocket to do all this....it's far better to secure it in situ as best as possible with your tens or hundred of millions of dollars.
