Results: The results revealed a high prevalence of chronic diseases of workers of the main group, as well as a relationship with the total accumulated dose and experience with sources of ionizing radiation. Excessive relative risks have been identified for diseases of the endocrine and nervous system, eye, ear, circulation, digestion and skin. Cardiovascular pathology represented by essential arterial hypertension and coronary heart disease, was the most characteristic of the uranium industry. Conclusion: In the studied cohort of workers, the prevalence of diseases depended on the length of work in the enterprise and the dose of radiation for diseases of the circulatory system, digestion, eye and nervous system. Diseases of the circulatory system, nervous, endocrine system, ear, skin can be classified as professionally conditioned.
