The article presents the typical results of investigations carried out for assessment of the modern radioecological situation in liberated territories of the Aghdam, Lachin and Kalbajar districts. Earlier studies have shown that the radioactivity of rocks in Karabakh varies depending on the composition and age of lithological-stratigraphic intervals. In general, the gamma activity of rocks in this area does not exceed the background significance characteristic of structural complexes of different ages of the Lesser Caucasus. During radioecological monitoring in the studied area, the measurement of the strength of the exposure dose of gamma radiation was carried out by the IndetiFINDER-2 dosimeter-spectrometer, and the strength of the ambient equivalent dose was carried out by the portable dosimeter-radiometer of МКС-АТ1125. As a result of the conducted studies, it was found that the radiation background in Aghdam and Lachin regions is within the norm, and only in soil samples taken from Istisu settlement of the Kalbajar region, the average value of the dose absorbed in the air (D), external hazard index (Hex) and the annual effective dose equivalent (AEDE) were higher than the limit values
