[Ischemic heart disease in workers of radiochemical industry chronically exposed to radiation dosage less than MPEL].

Prevalence of coronary artery disease (CAD) was studied in workers of atomic industry, who are exposed to combined radiation (doses hardly allowable for professionals). The occupational activities lasting for 5 to 38 years caused total gamma-radiation, doses of 0.01-1 Gy, plutonium-239 incorporation of 0.07-1.48 kBq. The prevalence of CAD, with consideration of Minnesota Code Criteria, equalled 10.9%. The authors analyzed the main risk factors for CAD. Dispersion analysis failed to find significant relationship between CAD and the total dose of external radiation and the level of plutonium-239 incorporation. The studies revealed reliable dependence of the CAD occurrence on the age and arterial hypertension.
