Is response to the semorandum 2f Jane 20 from dr. Libty to you abcut
the same subject aa this memcrandup, the data on the calcium content
ef the samples reported {a SWFL-53 will be obtained and forwarded tc
Br. Libby at the eerliest time possible. This information will permit
the calculation cf “strontium unite’ formerly called “sunshine units .
The calctum data wes act included in UVFL-50 as the purpose cf the
Yepert was to record the cbserved changes in radioactivity with tice
in ona area with one especies of organism.
Also, since the levels
of calcium in creb tissues are reasonably constant, the importance
of including the calcium data for these specific semples did aot
seam great at the time cf writing the report although ti is now
recognized thet these data will provide additional infcrmation.
I have been infcorwed that Sr. Libby's request thet calcium data
should eccompanxy all strontium data was received after UNFL-50
bad been completed but before the repert was published. Since or.
Libby’s request, the University of #ashington Laboratory hes reporte.
their date in terme cf strontium omits.
teference is made to Tabies
26 and {7 in “Radicective Contamination of Cartain Areaa in the
Pacific Gceas from Huclear Teats” (edited by Jr. Sunning); the table
submitted om February 11, i955, “Comparisen of Sr-S0 Levels in wand
Crabs Collected at fongelap Atoll in Jeiy, 19565 and July, L957°; the

of June 13, 1958 which includes a table om the “Se-$0 in the Skeletcns
