OSTI ID:4017294
Factors affecting the passage of /sup 90/Sr through the food chain to man and hazards from the chronic inhalation or ingestion of atmospheric /sup 90/ Sr are reviewed. Procedures for calculating the maximum permissible concentration of /sup 90/Sr for man are discussed. Four models of /sup 90/Sr turnover in the skeleton of adults were applied in calculations of the skeletal burden under conditions of chronic daily inthke of /sup 90/Sr in amounts found in the diet from 1953 through 1961. Calculated and observed values were compared for the United States, New York City, Canada, the United Kingdom, and Poland. Measured values provided a fairly good fit with the power function model of Sr retention derived from /sup 90/Sr studies in humans. A simplified model, based on the assumption that 2.5 to 3.5% of skeletal Ca is exchanged per year, also gave good agreement with observed values. Tenthtive values are given for the maximum permissible daily intake of /sup 90/Sr for the constant exposure of adults. (C.H.)
