Evaluation of Age and Gender Dependences of the Rate of Strontium elimination 25-45 Years after Intake: Analysis of Data from Residents Living along the Techa River
The Mayak Production Association released large amounts of Strontium 90 into the Techa River with peak amounts in 1950-1951. Residents near the Techa River ingested an average of {approx}3,000 kBq of Strontium 90. The affected people have been followed by Scientists at the Urals Research Center for Radiation Medicine. The whole-body content of Strontium 90 of {approx}15,000 individuals has been measured over a period of 24 years (1974-1997) using a special whole-body counter. This report evaluates the gender and age dependences of individual rates of strontium elimination. Data on persons who had been measured 12 or more times were selected for study. There were 108 men and 81 women older than 30 years who met this criterion. Individual measurement results were fitted to an exponential function and grouped mean averages of the rate of strontium elimination as a function of age for each sex were derived. The results may be used to develop a gender- and age-dependent model of strontium metabolism.
