This study investigates uranium concentration in urine among workers in different stages of Kazakhstan’s uranium production cycle—mining, processing, and fuel fabrication. A total of 619 urine samples were analyzed using inductively coupled plasma mass spectrometry (ICP-MS). The highest uranium concentrations were found in workers from in-situ leaching mining facilities. Statistical analysis revealed significant variability and skewed distributions across groups, with a proportion of workers exceeding the reference value of 0.9 µgL⁻¹. The findings highlight the need for ongoing biomonitoring and further assessment of occupational exposure, particularly among residents living near uranium production sites.
