For three decades, camera company Kodak had a secret deep inside an underground lab in its Rochester, New York research facility: weapons-grade uranium and a californium neutron flux multiplier. (No, not a flux capacitor.) They stored 3.5 pounds of the uranium, apparently not enough to make a nuclear weapon but still not something you'd expect to find in most corporate research labs. The Union of Concerned Scientists are, well, concerned. From CNN:
Kodak turned the material over to the government in 2007, under heavy security. But for more than 30 years, the company had a device called a californium neutron flux multiplier, or CFX, in a specially built labyrinth beneath Building 82 at its labs near Rochester, New York. The device was about the size of a refrigerator.
It was not a reactor, but rather a hunk of metal emitting radiation. Its purpose was to create a beam of neutrons to use for scanning and testing other materials. The device's primary source of neutron radiation was the radioactive element californium, but the stream of neutrons produced by the californium was multiplied by passing it through a lattice of highly enriched uranium U-235, whose nuclear fission released additional neutrons.
According to a spokesman for the Nuclear Regulatory Commission, Kodak's uranium was highly enriched -- to a level approaching 93.4%. That is the type of weapons-grade material that U.S. government agencies are trying to prevent terrorists from getting their hands on…
Kodak says it never intended to hide the CFX, and it was licensed by both state and federal officials. But the fact that the company was handling highly enriched uranium was never widely publicized.

It’s the end of an era, sort of: Fraunhofer IIS, the developers of the MP3 audio compression format, announced that they are ceasing their licensing program. In a blog post, spokesman Matthias Rose says that it’s had a good 20-year run and is obsolete. But it’s also true that the decoding patents expired last year, […]
Freddy deBoer writes that he’s been telling the same joke for years about Silicon Valley’s only product, which might be universalized as “At last, a way to verb with nouns on the internet!” But the social-media techopoly is stable, now, and so the venture capitalists have moved on to the three terrible trends that will […]
Alex Wood is an addict but won’t give up his smartphone. But he has five strategies for limiting its control over him: “I used to wake up tired. My body would ache and my head felt sore, like waking up with a hangover. Finally, I took control, like attending an AA class for addicts, I […]
While some people still maintain that everything in Apple’s walled garden “just works” and is immune to the rampant malware of the Windows world, the reality is different. The Mac’s growing market share has made it a much more viable target for malicious actors, and its built-in tools aren’t always enough to fix things. Drive […]
