I was watching a program on the Discovery Channel, and they talked about finding a shipwreck containing a whole load of "low alpha lead". It is apparently MUCH more valuable than the wheelweight variety--$30-40/lb and up. It is used for semi-conductor and other modern electronics manufacture, where low-level background radiation has to be kept to a minimum in order not to disrupt the chip's function. Apparently, the stuff can be manufactured, but also lead that is >100 years old or so can be a possible candidate for low alpha levels. Any of you guys ever heard of or know much about this stuff? Maybe lead CAN be turned into gold....
