Characteristics of the Uranium Cohort of Personnel of the Radiochemical Production of the Siberian Chemical Plant

Introduction: Professional contact with uranium, which is the main raw material element in nuclear power, creates a risk of adverse effects for personnel in contact with it.

In order to study the effects of uranium compounds on the body of personnel at nuclear facilities, it is necessary to create cohorts of people engaged in work with this radionuclide.

Objective of the study: To form and describe a cohort of radiochemical production personnel of the Siberian Chemical Plant involved in work with uranium in the period 1953–2000.

Material and methods: The cohort was formed on the basis of information from the regional medical and dosimetric register, which contains information on all current and former employees of the Siberian Chemical Plant (about 65,000 people).

Results: A cohort of workers in the radiochemical production of the Siberian Chemical Plant who worked with uranium compounds in the period 1953–2000 was created and characterized. The cohort included 205 people (151 men and 54 women). Medical and dosimetric information about the individuals included in the cohort was entered into the created database of the personnel of the Siberian Chemical Plant involved in working with uranium compounds in the period 1953–2000.

Conclusion: The formed cohort of workers in the radiochemical production of the Siberian Chemical Plant will allow studying the stochastic effects of uranium exposure on the body of workers who come into contact with uranium compounds as part of their professional activities (in particular, cancer incidence and mortality) and making scientifically substantiated conclusions regarding the role of this radionuclide in the occurrence of socially significant non-communicable diseases, primarily malignant neoplasms.
