Estimation of Radiation Induced Risk among Nuclear Workers - Liquidators on Chernobyl Accident in Low Dose Range
Purpose: To obtain adequate estimations for additional relative risk in recalculation on 1 Sv in two dose ranges: up to 200 mSv and up to 500 mSv. Materials: Prevalence of malignant disease of workers of the nuclear industry - liquidators of the accident at Chernobyl Nuclear Power. For this purpose, methods of cohort analysis were used (EPICURE software). Results: The obtained results have demonstrated, that in some cases estimations for the risks, obtained via the modified formula, are more realistic, in other cases both estimations have close values. Conclusions: The analysis has not shown the correctness of the procedure of risk estimation transfer from one dose interval on another dose interval because of nonlinear dependence of risk versus dose. One can use the modify formulas: y = a + bx.
