[ RadSafe ] Australian Uranium in Antarctic Ice ?

[Dan McCarn]

Those same dusts, if they are from Roxby Downs (Olympic Dam), would also have elevated levels of copper, silver, & gold.

Ice cores from Greenland have been shown to have elevated lead concentrations in strata corresponding to the Roman Empire and are interpreted as reflecting the processing of lead ore and the use of lead by the Romans. And we know (as someone else mentioned earlier) that African dust has been tracked across the Atlantic, as has Chinese dust across the Pacific. So the thought that Australian dust might make its way to the Antarctic Peninsula is certainly reasonable - if the uranium is mined or processed in such a way that generates dust.
