Abstract

The appearance of autoimmune thyroiditis in children living in the Chernobyl contaminated areas of Kaluga region has been treated through the determination of antibodies to human thyroid microsomal antigen. The 6-year-study of antimicrosomal antibodies has shown that among the examined children the greatest number with elevated antibody level was reported in 1987 (4.8%). The quantity was then decreasing till 1990 and later there was a significant rise again. Using data of direct dosimetry of thyroid gland, we detected a reliable increase in occurrence frequency of antimicrosomal antibodies in children with the irradiated thyroid gland as compared to those whose thyroid gland had not been exposed to iodine.

Key words
Autoimmune thyroiditis, children, Kaluga region, Chernobyl accident, antibodies to microsomal antigen, thyroid gland, antimicrosomal antibodies, direct dosimetry data, radiation load, radioactive iodine.
