effects gradual progress within all period extent passed since the Chernobyl NPP accident. Direct time link to radiation factor, dose-dependence and dose threshold presence are characteristic signs of non-stochastic radiation effects.
2. Early primary functional thyroid reaction on radiation was observed within first year after accident presented through “euthyroid” hyperthyroxinemia, short-term “stress” hyperthyreotropinemia with further interconnections restoration in thyroxin-thyrotropin system.
3. Hyprethyroxinemia were in proportional dependence upon to the dose and inversely proportional to the age of examined persons.
4. Primary thyroid reaction on radiation, immune shifts of first years period after accident and further revealed in ultrasound study thyroid structure alterations (beginning from 1990 - 1991) indicated the chronic with high probability autoimmune thyroiditis genesis onset.
