Air pollution has a serious impact on human health. Deterioration of the air environment causes 7 million premature deaths annually. Despite the active implementation of various environmental programmes and technical resources aimed at preserving and protecting the environment from anthropogenic factors, over 90% of the world's population live in cities that do not meet the air quality recommendations of the World Health Organisation (WHO). Intense and constant technogenic load necessitates continuous monitoring of atmospheric air quality. Sufficient, systematic and representative information is needed to study the spatial and temporal distribution of substances in the air basin, to predict pollution levels and to make correct environmental decisions. Environmental monitoring is a tool for obtaining such information. In this work the analysis of influence of radioactive waste of nuclear power plants on a radiation level of environment is executed and the tasks of its ecological monitoring in areas of location of the enterprises of nuclear power industry are considered.
