Summary: The review of regression models for the approximation of dependences "dose- response" was performed based on ecotoxicological results. The advantages and deficiencies of different models as well as the problems arising both in modeling and subsequent interpreting results are discussed for the purpose of ecological rationing and estimation of negative influence risk. Search procedures of best dependences based on statistical criteria and the methods of uncertainty estimation of calculated parameters are shown. Construction of models is illustrated in detail using the analysis of toxicity results of soil samples received from uranium mines tailings in Kadzhi-Say province (Kyrgyzstan). Threshold values of activity for U-238 and Ra-226 radionuclides providing the minimum probability of ecological risk were determined.
