Dear Herb:
We are sending 1h assorted sam les from the Pacific for analysis.
munbers are 025, 1027, 1,029, j031, 4033, and 4038-6.
The
These samples
are to be analyzed for total beta activity for Sr-90 and for caledum.
We would like these to be given highest priority in your laboratory
as the need for the results Ais Quite immediate.
I am enclosing with this letter a sheet specifying our pecomendations
for total beta measurements, In addition, we would like to specify :.
that these samples are to be vet ashed rather than dry ashed due to
their small size.
‘The activity in all cases should be high enough-so
that good statistics can be obtained with short counting periods.
I believe that there will be further samples of this type in the near
future and we will pass them along as soon as received.
‘Sincerely,
John H. Harley, Chief
Analytical Branch
Enclosure!
