Радиогеохимические особенности аэрозольных выпадений в районах размещения предприятий теплоэнергетики (юг Западной Сибири)
The paper presents the results of study the radiogeochemical features of particulate matter deposited in snow cover around of thermal power plants. Instrumental neutron-activation analysis was used to study U and Th contents in the samples of particulate phase of snow. It was revealed that U and Th contents were exceeded the background values from 2 to 43 times in the samples. These results demonstrated the anthropogenic origin of the elements. It was identified that U occurred in mode of phosphates and oxides in the samples. Uranium isotopes were mainly correlated with Fe and Mg oxides and insoluble fractions.
