Abstract

This paper, presents the results of the radioecological assessment of aquatic and terrestrial ecosystems including agroecosystem in the area of location of the joint stock company «Siberian group of chemical enterprises» (SGChE). To measure the content of radionuclides in components of terrestrial (forest, meadow, agricultural) and aquatic ecosystems on the area of location of the Proryv project pilot demonstration energy complex, field and desk research was performed. The content of 137Cs and 90Sr in surface waters was 0.5 Bq/dm3 and 0.15 Bq/dm3 respectively. Volume activity of 239,240Pu in surface waters ranged between 4.4x10-6 Bq/dm3 and 126x10-6 Bq/dm3. Average content of 137Cs in soil within the 30 km area of SGChE location was 13 Bq/kg, and 58.5 Bq/kg in terrestrial vegetation. There was the need to perform detailed analysis of artificial radionuclides content in water bodies within the 30 km area of the SGChE location. Natural and artificial radionuclides, as well as the detected maximum massic activity in the components of the natural environment within the area of SGChE location was below regulatory levels.

Key words
radioecological survey, environment, water, sediments, soil, vegetation, radionuclides content, massic activity, agricultural products.
