摘要: The East-Ural Radioactive Trace (EURT) is a result of the Mayak Production Association accident that occurred in 1957 Russia. Radiological assessment improves interpretation biological effects exposure to ionizing radiation. Therefore modeling approach was used estimate dose rates on Leonurus quinquelobatus, Silene latifolia, Stellaria graminea and Bromus inermis. Soil-to-organism transfer parameter values are delivered from empirical data 90Sr 137Cs soil vegetative plant mass activity concentrations. External internal whole-body were calculated using deterministic (The ERICA Tool-Tier 2 R&D 128/SP1a) probabilistic 3) methods. total rate for herbs under 100 μGy h−1 at most polluted site. absorbed increased 43–110 times (Tier different herbaceous species along pollution gradient. Based these data, it can be concluded populations currently exist low-level chronic EURT area.
