Ecological Systems and Devices Annotation << Back NEUTRON ACTIVATION ANALYSIS OF NATURAL OBJECTS SOUTHERN ARAL SEA A. Zhumamuratov, M.A. Zhumamuratov On the bases of experimental investigation of γ-irradiation spectra of probes activated with integral neutrons fl ow at different time factors the selectivity coeffi cient is calculated for every probe and elements. New data are obtained on mean content of more than 30 chemical elements in the content of natural water, soil, bottom sediment, aerosol dust and atmospheric precipitation. A background level’s of the elements content in studied objects, their dispersions of the diffusing, track record of the change of the degree of mineralization of water, sources of the contamination of the objects of environment by about 30 chemical elements (lethogen and anthropogenic) are established. Keywords: Neutron-activation analysis; Aral crisis; biogeochemical objects; objects of environment; natural water; soil; bottom sediment; aerosol dust and atmospheric precipitation.
