HSAs JHHikrw December 18, 1958 Dr. Robert A. Conard Jr. Medical Divisicna Brookhaven Natlonat Laboratory Assoctated Universities, Inc. Upton, Long Island, New York Dear Or. Conard: fam enclosing 4 fabfe of the complete data thet we have on the Marshall tstand food samples, These samples were analyzed in our laboratory and afi Information avaliable to us is reported, ft Is my personal feeling that these values ere extremely high tf we are to consider them as being a steady diet. if we had to estimate the present average level of Stronttum90 in. the Amertean diet #4 would be below 10 pyc $r99/G Ca. The average vatue in the Marshatlese samples is of the order of 900 and this might tead to a bone confent in children of greater than 100 ppc Sr9°/g Ca. Naturatty these figures are purely conjec tural but are based on comparison of the appropriate fevels In American food and bone, and the food samples mentioned. We would be happy to analyze further samples ff they are required to clarify the general picture. Sincerely, John H, Harley, Chief Analytica! Branch Enclosures j. cc Table Cc. L. Dunham, DBM G. M.
