Abstract:
The main objective of current study is to assess the dose burden and health status of workers at the
uranium processing hydrometallurgical plant in order to develop measures aimed at reducing their
incidence. This article presents the results of radiation monitoring and data on the health status of
workers at the hydrometallurgical plant of the Stepnogorsk Mining and Chemical Combine (SMCC). The
data of the accumulated effective dose for the entire length of service, as well as data on the incidence
rate for the period 2013-2019, obtained from the base of the Industrial Radiation and Epidemiological
Register, have been analyzed. Based on the results of measurements of the uranium content in urine, the
expected effective dose of internal irradiation of the enterprise personnel was calculated. The assessment
of the health status of workers was carried out based on the materials of outpatient and hospital visits,
as well as the results of mandatory periodic medical examinations over the past 5 years. Based on the results, an excess of the expected effective dose of internal irradiation was revealed based on the analysis of a urine sample by 3 times. The most typical for the studied contingent of the main group turned out to be diseases of the eye and its adnexa (23%).
