"The author presents the results of radiocarbon dating of burials from the Sintashta cemetery near Mount Berezovaya (Bulanovo) and Tanabergen II in the steppe Cis-Urals. The series consists of 10 calibrated radiocarbon dates, three of which were obtained using AMS accelerated technology. As a result of the implementation of statistical procedures, a chronological interval for the functioning of necropolises was established within the அண். 2200–1770 BCE".
