RESULTS OF IN VIVO MEASUREMENTS OF STRONTIUM-90 BODY-BURDEN IN URALS RESIDENTS: ANALYSES OF DATA OBTAINED IN 2006–2012

A part of the Urals territory was contaminated with 90Sr and 137Cs in the 1950s as a result of accidents at the “Mayak” Production Association. The paper describes the analysis of in vivo 90Sr measurements in Urals residents. The measurements were performed with the use of Whole-Body Counter SICH-9.1M in 2006–2012. Totally 5840 measurements for 4876 persons were performed from 2006 to 2012; maximal measured value was 24 kBq. Earlier, similar measurements were performed with SICH-9.1 (1974–1997). Comparison of the results obtained with SICH-9.1 and SICH-9.1.M has shown a good agreement of the two data sets
