a _ 12000 as evidenced by the alpha meter read~ ings and these conteined en average uranius - oontamination of 1,663 micrograms per gram. The remelt copper showed neglieg gible surface activity and, as we expected the remelt copper. -. showed a very amall percentage of uranium = residual uranium per gram of copper and thie compares very favorably with the vre-Atomis Energy produced copper semple,. Next slide, please. We found thet the contaminated aluminum showed the highest-amount of cone tamination of any of the nenples that we analyzed, 4980 micrograms of U per gram, The remelt showed considerable surface contamination as evidenced by both the drillings and also by the Juno meacurements, The slag contained anproximately half the contemination shown in the original slag and thia is probably due to the fact of aluzinun’s affinity for oxygen, having an affinity greater than any other metal ore including ureniun, And therefore the uranium was not allowed to oxidize and could not come off in the slag. 82
