[en] The manmade radioactivity of the environment in the Danube basin in the Kozloduy NPP area is due basically to the presence of ⁹⁰Sr and ¹³⁷Cs in specific concentrations for the global atmospheric depositions and the environment contamination in result of the Chernobyl accident. The influence of the liquid radioactive releases on the manmade radioactivity of the water eco-system in the lower Danube (after the NPP discharge canal) doesn't differ significantly from the registered for the first time in 1996 changes in the same radionuclides content. They are the cause for the increased ¹³⁷Cs content in the Danube water next to the discharge canal and for the presence of nuclear fission products and activity in the bottom sediments. The ⁹⁰Sr content doesn't exceed 10 Bq/m³ for rivers' water, 1.5 Bq/kg for Danube fish and 1.6 Bq/kg for bottom sediments. No significant quantitative changes caused by the NPP gas-aerosol radioactive releases are registered. The assessment of the population irradiation around the Kozloduy NPP area presents less than 0.15% of the annual irradiation limit for the population - category B, according to BRRP-92 - 1 mSv/y and it is under 0.1% of the average background personal irradiation of the natural radiation background in the country - 2.28 mSv/y. The Kozloduy NPP operation during the whole period has led to an insignificant increase of the background irradiation of the population
