Bob, If a particular test or type of analysis is sampling the surface, but is done in such a way that a natural mechanism can bring mobile elements from deep inside a structure up to the surface, then the more volatile components could appear to have much higher concentration than they should.
From: Bob Cook If I am not wrong, the laser activation indicates Zn is 0.004 mass % vs the suggested 4%—more than an order of magnitude LOW!—more like 3 orders Low! I checked the table of mass % and it adds to 100 percent. From: Eric Walker <mailto:[email protected]> I do not think there was any report of very much Zn in the fuel. If there was Zn-64 in the samples tested it was not apparent from the report. In fact as I noted yesterday, Zn was on the order of .01 percent. It was not anyway reported near 4 % per my review of the AP report translated by Higgins. . As I attempted to show, even though the total amount of zinc reported in the ICP-MS analysis was small, it was of an order of magnitude to potentially explain part of the mass 64 balance. Eric
