Box 10901 _ Pittsburgh 36, Pennsylvania Dear Mr. Kruger3 We are sending 17 assorted samples from the Pacific for ana The numbers are 1,02), 1026, 028, 1030, 032, 03h, 4035-7, and OL7-She These samples are to be amlyzedfor total beta activity for Sr-90 and for calcium. We would like these to be given highest priority in your laboratory as the need for the results is quite inmediate. — I am enclesing with this letter a sheet specifying ow recommendations for total beta measurements. In addition, we would like to specify that these samples are to. be wet ashed rather than dry ashed due to their small size. ‘the activity in all cases should be high enough soe 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 pess them along as secon as received. . Sincerely, John H.
