Earlier today, David told you about a news story that's everywhere right now: The fact that the Kodak company ran a small nuclear facility at its research lab in Rochester, New York.
The facility closed down in 2007, but I can totally understand why this story interests people. It's nuclear! And it is really weird for a corporation to be sitting on 3.5 pounds of uranium. Like David said, this is unusual today.
David did a good job covering this in a sane way. The TV news I saw this morning at the airport ... not so much. That's why I like the detail provided the Physics Buzz blog, where Bryan Jacobsmeyer explains, better than I've seen elsewhere, just what exactly Kodak was doing with their nuclear system. Turns out, it's really not all that odd for this specific company to own this specific piece of equiptment when they did. That's because of what Kodak was. We're not just talking about a corporation in the sense of middle managers and salesmen. We're talking about original research and development—a job for which a californium neutron flux multiplier is quite well suited.
In fact, these research reactors can be found on several university campuses, and they are operated under strict guidelines without any nefarious intentions.
Researchers working at Kodak wanted to detect very small impurities in chemicals, and Neutron Activation Analysis (NAA) proved to be one of the best techniques to find these impurities. During NAA, samples are bombarded with neutrons, and elemental isotopes from the sample will absorb a small fraction of these neutrons.
Many of these stable elemental isotopes will become radioactive after gaining a new neutron; consequently, they will emit gamma rays. With the right equipment, researchers can measure the precise energy levels of this radiation and narrow down which elements are in the sample.
Basically, it provided a way to sift through the components of a sample at a molecular level, and spot the things that shouldn't be there. Originally, the lab used just californium. Later, it added uranium plates that helped make the system more powerful.

In the late 1960s and 1970s, the mind-expanding modus operandi of the counterculture spread into the realm of science, and shit got wonderfully weird. Neurophysiologist John Lilly tried to talk with dolphins. Physicist Peter Phillips launched a parapsychology lab at Washington University. Princeton physicist Gerard O’Neill became an evangelist for space colonies. Groovy Science: Knowledge, […]
In a lead editorial in the current Nature, John Wilbanks (formerly head of Science Commons, now “Chief Commons Officer” for Sage Bionetworks) and Eric Topol (professor of genomics at the Scripps Institute) decry the mass privatization of health data by tech startups, who’re using a combination of side-deals with health authorities/insurers and technological lockups to […]
The Wall Street Journal reports that storytellers—people with a natural inclination to craft concise yet compelling narratives without rambling—were found to be hot by science. Feels good to be a writa. The results were the same across all three studies: Women rated men who were good storytellers as more attractive and desirable as potential long-term […]
