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=

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.
