Распределение урана и тория на территории правобережья г. Новосибирска по данным анализа листьев тополя

Abstract

In the course of biogeochemical monitoring studies using a set of methods, data were obtained on the distribution of Th and U in the poplar leaves (P. balsamifera L.) on the territory of Novosibirsk. In the right-bank part of the megalopolis, the distribution of Th is influenced by the geologic factor - outcrops of Paleozoic granites characterized by an increased content of natural radionuclides. The U distribution is affected by the technogenic factor localized near the nuclear fuel cycle facility. The quantitative regularities of changes in U concentrations as a result of the transport of aerosols from an unorganized ground source have been established.
