Abstract
The topic of radiation safety is relevant for Kazakhstan given the Soviet history of nuclear testing. However, radiation indicators also depend on many other factors, both man-made and natural. The results of comprehensive research on the territory of Northern Turgai, which is part of the Turgai trough, are presented. Administratively, the research area occupies most of the Kostanay region, from the south-west the Aktobe region, in the east the North Kazakhstan and Akmola regions. An integrated approach to the study of radiation safety was used, taking into account the geological situation and anthropogenic load of the region.
