Distribution and transport of radionuclides in the terrestrial ecosystems, zone of accident on the Urals

摘要：

In 1957 a serious nuclear accident took place in the Southern Urals. About 74 PBq of radioactive substances were released into the atmosphere, which resulted in the Eastern Ural Radioactive Trace (EURT). The data of our study have shown that the concentrations of <90>Sr and <137>Cs in the soils of the frontal part of the EURT are 55-260 and 1.1- 5.7 kBq/kg, respectively. The accumulation coefficients for <90>Sr in all species of plants were significantly lower in the impact zone, than those in the buffer and background zones.
