McGruber writes "The Rochester (NY) Democrat-Chronicle has the interesting story of the Eastman Kodak Co.'s Californium Neutron Flux Multiplier, which was housed in Building 82 of Kodak Park in Rochester, NY. The multiplier contained 3½ pounds of highly enriched (weapons-grade) uranium. Kodak used it to check chemicals and other materials for impurities, as well as for tests related to neutron radiography, an imaging technique. From the article: 'When Kodak decided six years ago to close down the device, still more scrutiny followed. Federal regulators made them submit detailed plans for removing the substance. When the highly enriched uranium was packaged into protective containers and spirited away in November 2007, armed guards were surely on hand. All of this — construction of a bunker with two-foot-thick concrete walls, decades of research and esoteric quality control work with a neutron beam, the safeguarding and ultimate removal of one of the more feared substances on earth — was done pretty much without anyone in the Rochester community having a clue.'"
