MEDICAL RADIOLOGICAL CONSEQUENCES IN PERSONS EXPOSED TO LOW DOSES OF IONIZING RADIATION
The article summarizes the results of the clinical examination of the liquidators of the accident at the Chernobyl Nuclear Power Plant (CNPP) with diseases of internal organs and workers of typical nuclear research reactor (TNRR) exposed to low doses of ionizing radiation. A total of 117 of the liquidators of the accident at the CNPP with documented absorbed dose of external gamma-radiation on average 163.06±9.54 mGy for 3.1±0.9 months and 24 TNRR workers with cumulative dose of external gamma-radiation on average 78.93±11.84 mGy for 17.6±1.6 years were examined. Physical examination of the patients, the evaluation of diseases of bronchopulmonary and cardiovascular systems, digestive system, blood, central and peripheral nervous system with antemortem and autopsy morphological diagnosis were performed. The main results of the study included detection of pathological changes in microvasculature, from vasculopathy to productive vasculitis in biopsy material from the shin, shoulder, myocardium of the right ventricle. Generalized damage of microvasculature, apparently, is the main cause of clinical and functional characteristics of internal diseases identified in liquidators of the accident at CNPP.
