of the samples; also be responsible for the analyses of the samples to assure full interpretation of the data. in this opinion. Dunham and Seymour concurred It was generally agreed that duplicate samples should be exchanged between laboratories in order to evaluate the variability of results of analyses made by different labs. Dunham suggested University of Washington group run urine samples for Conards group in the future. Held indicated that low level beta-counter would not be available for about six months. was accepted as satisfactory. This time Conard expressed the desirability of collaborative effort between the medical and ecological survey groups for the spring surveys. Conard suggested starting date between 1 - 15 March. Because of teaching commitments of some U W personnel Conard agreed to try to set starting date between 15 February and 1 March. Total time of survey to be about two weeks at Rongelap and 3 or 4 days at Uterick. Dunning indicated possible usefulness of Uterick data to ecological surveys in gaining some information on fractionation of fallout. Dunham stated that efforts should first be made to secure a suitable vessel from the Dept. of the Navy. Anton said that under new regu- lations of "industrial funding’ may require that AEC pay for vessels operation. Dunham said that decision as to selection of vessel should be deferred until Conard had received definite word from the Navy. For the U. W. summer survey at Rongelap use of the ‘Aloto’ assigned to Holmes and Narver seemed most feasible. Use of this vessel will cost $1250. 00/day, or about $20, 000.00 for the summer survey. Dunham said this seemed to be a reasonable expense. The desirability and difficulties of obtaining human bone samples was discussed. in bone. Conard has two such samples; one male, died 1956, 0.35.U.. Conard has also been collecting deciduous teeth. Bruner explained the necessity for using all parts of teeth for comparative purposes. The cemented portions contain more Sr99 than other portions. Cohn presented data concerning radioisotopic levels in Rongelapese: Background of whole body counter for May 1958 shows definite Lal40 peak indicating fallout from Hardtack.
