Estimates of /sup 90/Sr intake via the total diet in New York City and San Francisco have been made since 1960 from quarterly food samplings and average consumption statistics. The dietary intake of /sup 90/Sr has decreased from the maximum levels attained during 1963-1964, but the decline has become more gradual in recent years due to the continuing small amounts of /sup 90/Sr deposition and the little-changing cumulative deposit of /sup 90/Sr in soil. The annual intake in 1982 averaged 5.4 pCi/day (0.20 Bq/day) in New York, and 2.6 pCi/day (0.096 Bq/day) in San Francisco, little changed from the previous year. Further gradual reductions in /sup 90/Sr intake are anticipated during 1983. 1 reference, 7 figures, 4 tables.
