— 80 “Hy oh,J- me sample that was obtained, produced before 1942. In our surface measurements with the alpha meter, 1t showed that we had an average alpha contemination of approximately 12000pver hundred centimeter square smesera taken and analyzed assimilation count showed that we obtained a emeer, a removable cone= tamination of this figure, (Indicating) Analysis of the duplicata drilling averaged 2900 and 25 microgram unite per gram of nickel, A remelt showed almost neglig- 4ble of contamination on the alpha meter, A smell amount of removable alpha as evidenced by the smesrs and a walue of remneilt residual uranium contamination of 1,25 micrograms U per gram of nickel which 1s comparable with the pre-produced nickel obtained from the National Bureau of Standards of 2/10. - The top surface contained 1,1 micro=- grams U, while the average of the samples was 1.25. . ‘ Next slide,please, The nickel stainless melt wag come posed of ten per cent nickel, ninety per cent
