GENERAL G7 ELECTRIC 41088¢ Reveuber 9, 1956 Atomie Energy Comelesion Division of Biology end Medicine Veshing 25, B.C. Attention: W. 3B. Clans, Chief Biophysics Branch Dear Valt: oe pn eNES aya ABLE ap) COR AMAR e Bielogical Survey of the Preifte In reply to your phone enll of Hovesber 7, 1956 we are enclosing a conplete list: of the sexples received te date from Dra. L. A. Donaldson and R. R. Harry surve;' The iafereation was ebtained from sanple labels or lists supplied by the groupe responeibie for collection of the epecinens. in the future we will subalt sosth reports of al] samples reeeived during that peried. The absence of a report vil indicate that ac seuplee were received by the laberatery. Alee as you indicated oaly apperent general trends with reayect to fluid tremsport of radioactive substances vill be included tz the monthly progress statements. Closer serutiny of the analytionl data confirmed ny statenants by phone that for the samples received to date there ia no apperent correlation of the fluid trans. port ef redionetivity with time since detonation. Nowever, if the iscchromic 11 of the Horth Equatorial Current (Geo. Vanderbilt Foundation anp) approxiante the actual tins of truvel, then ne time correlation would be shown by the samples analyzed. There are taelated cases of positive radioactive substances in Biclogical sample from the Palas, Gaipen, Guam, Yap end Ulital stations. Phe speredic pattera of these positive spesiuens throughout the entire eallestion peried precludes cor- relation with tine, and tadicates a souree other thas fluid transport of debris frou the "Re@wing” series. Alse ease indicated tn ow phone conversation the beterogemeity of the results obtained to date on Dr. Donaldeon's samples preciudes any conclusive statensets as to patterns and trends at the present ties. It agpears thet all analytical werk euet be conpleted before an accurate evaluation could be asée.
