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.
