Hi Jack, You know looking back is always memorable. Years ago I was a lab supervisor of sorts. We did work for neuclear facilities and other customers. One of out specialties was Pulse Height Alpha Spectrometry. It was more of a surficial analysis that worked much better for gold than neutron activation. We used a Californium source for radiation energy. The source was the property of the US Government; as I understand that particular isotope of Californium was worth about a million an ounce or so. Any way we had that capability. Some guys brought rocks by that showed high levels of gold. These guys came from Westinghouse's Geophysical labs located in Boulder, Colorado. Westinghouse did a lot of of military related geological/instrumental research work. Well, here was the argument. The rocks contain high amounts of gold sayeth the physisist and nuclear chemists; no they don't sayeth the assayers. However, with a whole lot of work that was of no interest to anyone paying the bills, the gold was finally extracted refined and weighed. I think that Ledoux does that kind of spectrometry since they do nuclear fuels analysis. But I will bet they don't use the method to assay rocks. mike
