There is an increase in primary and overall mortality in the Sverdlovsk regional areas exposed to eastern-Urals radiation traces. The children mostly commonly have diseases of the endocrine and nervous systems, sensory and respiratory organs. The adults have predominantly neoplasms, diseases of the nervous, digestive, and urogenital systems and sensory organs. In the study period (1990-2000), morbidity considerably increased in the Kamensk Region marked by the highest radioactive contamination. There was an association of the morbidity rates with environmental (Bogdanovichsky District) and socioeconomic (Kamensky and Bogdanovichsky Districts) factors and with level of radioactive contamination (Kamensky and Bogdanovichsky Districts).
