In this study, the existing radioecological state of the Mothballed uranium mine was assessed. The levels of radon concentration in the air of residential premises were determined and dose loads on the population were calculated using the example of Saumalkol village, Kazakhstan located in the zone of potential influence of a mothballed uranium mine. Radon concentrations were measured in living rooms and bedrooms on the ground floor. The contribution of indoor radon to the annual effective inhalation dose for the residents of the village ranged from 9.3 mSv to 145 mSv in winter and from 1.8 mSv to 18.7 mSv in the warm season. The estimated average annual dose for adults in Saumalkol was higher than the world average annual effective dose of 1.2 mSv due to indoor radon inhalation.
