These new data appear in draft reports by the Southwestern Radiological Health Laboratory (SWRHL) and the University of Washington. The results were to be rechecked through an exchange of soil collections between SWRHL and the University of Wash- ington and analyses of samples collected in 1967-1969 surveys for which plutonium determinations have not been made. (These results are to be available in about two weeks.) A possible need to collect additional soil samples and to sample plutonium in air was cited. Meeting on Followup Actions: A meeting was held on March 25, 1970, to discuss possible followup actions to be taken on the matter of the Bikini soil samples. were: -Dr. Spofford English Mr. Dr. Dr. Mr. Mr. John Erlewine John Totter Martin Biles Robert Catlin Herman Roser .- Those attending Dr. Gordon Dunning Dr. Mr. Mr, Mr. Mr. Nathanial Barr Tommy McCraw Marion Johnson William Hughes Robert Newlin The discussion centered on steps to be taken to confirm the higher levels, the need to increase the number of soil samples available for analysis and to obtain air sampling data, the disposition of the two draft reports which contain the most recent soil data (the higher levels obtained in 1969), the approach to be taken in planning for collection of additional soil samples and air samples, the need to coordinate any field trips with the Department of Interior, “and the need to develop statements for use in answering any questions about the field trip. fcons5 ' foas ‘ea 1 ' ~ a 4
