Abstract

An algorithm and formulas to estimate non-regulatory stochastic risks (for biota and humans) have been derived. These were used to assess radiation risks for meadow plants within the Semipalatinsk Test Site (STS). It has been shown that on small plots with relatively high radiation levels (∼ 0.25 mGy/h) the radiation risks of death of radiosensitive plants (leguminous and coniferous shrubs) have a noticeable value (> 2%). In the other STS area, radiation is not a danger to the vegetation.
