RESUMO
The examination of 468 children and adolescents estimated frequency and structure of chronic pathology of the pharyngeal ring in long-term exposure to low-dose radiation. Chronic disease of the tonsils and adenoids was detected in 194 children (45.4%). Chronic tonsillitis was diagnosed in 142 (33.3%) examinees. 31.7 and 59.9% cases had compensated and subcompensated disease. Decompensated process took place in 8.5% cases of chronic tonsillitis. Hypertrophy of the palatine tonsils and adenoids was detected in 96 (22.5%) children. High incidence of lymphadenopathy of the neck in combination with chronic tonsillitis and tonsil and adenoid hypertrophy was found. Structure of chronic pathology of the lymphoid pharyngeal ring correlated with internal radiation dose. Comparison of postnatally and antenatally radiated children demonstrated less frequent incidence of affected lymphoid pharyngeal ring in children born before the Chernobyl accident.
