“…Eleven samples (from 0.98 to 1.84 1.84 µgL −1 ) have a value increased up to 2 times, seven samples (from 2.00 to 3.53 1.84 µgL −1 ) up to 4 times, and the rest (from 5.84 to 7.09 1.84 µgL −1 ) to 7 times. In early studies, the concentration of uranium in urine of the SMCC workers was found to exceed the conventional norm by more than 30 times, the reason for this was worn-out equipment that led to the excess of the permissible volumetric activity of radionuclides (1.5 times) from the permissible norm [4]. As part of this study, workplace radiation monitoring reports for 2020 were analyzed (indicators such as dose rates, long-lived alpha-particle activity concentrations and equivalent equilibrium volume activity of radon (EEVA) are within acceptable levels.…”

“…The uranium concentration in the urine samples was introduced at the test laboratory of radiochemistry and radio-spectrometry using mass spectrometry (ICP-MS) model 7800 (Agilent Technology, USA). The mass spectrometry parameters and the method have been explained by early studies [4]. Three aliquots were taken from each urine sample and analyzed.…”

“…Due to the absence of a norm for the content of uranium in urine in the Republic of Kazakhstan, the permissible concentration of uranium in urine was taken as 0.9 µgL −1 . This value is based on previous studies [4] and is accepted as a convention by the U.S. Nuclear Regulatory Commission [5].…”

The main purpose is determine and evaluate uranium concentration in urine of the inhabitants of nearby settlement of uranium mining sites and workers of uranium processing sites. As uranium enterprises working in Stepnogorsk of Akmola Region and its exploitation could be a risk of radiation exposure for the workers as well as for the local population, monitoring of biosamples could allow information about the exposure to uranium for the workers and inhabitants. Workers and inhabitants of male genders were asked to collect 24 h-urine samples. The concentration of uranium in urine was measured in mass spectrometry (ICP-MS). Uranium concentration in urine samples from workers values ranged from 0.05 to 12.5 µgL −1 , for Akmola region inhabitants values ranged from 0.10 to 0.60 µgL −1 . The results of concentrations of uranium in the urine of inhabitants living near SMCC were comparable to values reported in other studies. The concentration of uranium in the urine of the workers had slightly elevated values, comparable to the conditional norm of 0.9 µg/L.

“…Special attention is paid to the settlements which located on the territory affected by mining activity. There are notice radiological risks both in terms of radiation doses and in the others factors affected [2,3]. Key problems have been associated with the transport of Natural Occurring Radioactive Materials (NORMs) in aquatic and terrestrial ecosystems, where radionuclides are transferred from air, water, and soils into plants, animals and finally to man [4].…”

The Stepnogorsk area Northern Kazakhstan has a long history mining activities. Mining activities have lots of environmental and health impacts. The aims of this study were to characterizing the general radiological situation of the area and evaluate radiation exposure by scenarios in settlements. In this study radiological assessment was performed for critical group living in the territory contaminated with radionuclides; working and studying at school located on territory former mining site. The annual dose burden is 2.5 mSv y−1 in Zavodskoy, 1.9 mSv y−1 in Kvartsitka and 3.6 mSv y−1 in Aqsu; and exposure from radon is around 11 mSv y−1 at the ground floor, and for teachers - up to 12 mSv*y−1. At settlements, however, under the hypothesis that all food contaminated with radionuclides and vegetables is cultivated locally in the territories with high background level, exposure from ingestion is 9.1 mSv y−1 in Zavodskoy, 8.3 mSv y−1 in Kvartsitka and 11.5 mSv y−1 in Aqsu. The combined effects of environmental problems have culminated into health problems. There are such possibility of the higher prevalence of cardiovascular, digestive and respiratory systems so it is necessary to evaluate or protect people living in Stepnogorsk area.
