SECREF == sH-1gs0-aBe ONCLASSIFIED Thus, the SUNSHINE prdjéctMts a whole framework of research bearing on the creation of an environmen‘al situation and man's involvement. TI. Biological Sampling A unique set of data has become available, bearing on man, or at least prenata. man. and his ftovolvement with a sr? contaminated environment. There are the Chicago baby measurements summarized in Appendix A. The results indicate so far that newoorn babies in the Chicago area have about 1/¢th SUNSHINE Unit of 3r” o- about 1/6000th of tolerance. On the basis of the original SUNSHINE es'.imate of an even distribution of 2.5 x 10" MT of debris to bring the world population up to tolerance, 4 MP would give the Chicago babies the observed deposition. The inte- grated National Test Site detonation is of the order of 400 KY. Thus, one must assume a significant contribution from the Pacifiic tests or an extremely umeven distribution from the continental teste. It is interesting to note, however, that regardless of the origin of the observed Sr°”90 in soil, there does appear to be a correlation between the measured soil values and the observed baby samples. This correlation is based on data received through January 4, 1954. (+) In Project SUNSHINE Bulletin Mo. 5 the gr assays on 44 premature or stillborn Chicago babies are reported by Professor W. FP. Libby. Wine of these measurements were mode early in the project, while techniques were being developed ani tested, and are reported as less than or equal to specified values. The birth dates for the first 43 samples span the period from July 26 to November 2, 1953. ‘The birthdate of the 44th specimen wes oot stated but it was delivered to the project on December 4, 1953. grems. The ash weights for individual samples vary from 13.5 to 90 The gr? assays vary from 0.043 " 0.024 to 0.4 2 0.1 SUNSHINE }O4S 340 SECRET eR isge sere ———— a= eee 8 er _ —nme eenaht: RN UNCLASSIELED | ANL
