[Study of the consequences to the health of the Urkutsk Region's population from nuclear explosions at the Semipalatinsk testing site].

Analysis of archival records on the activity of diurnal plane-tables from the region's weather stations revealed local radioactive fall-out in the near-Baikal areas from the nuclear weapon tests carried out at the Semipalatinsk testing site. Examination of mortality rates in the settlements exposed to the tests showed that the maximum rates of overall and lung malignancy mortalities were observed in 1960-1979; the mean radiation dose in the exposed settlements were estimated to be 580-850 MeV.
