Uranium and thorium determination in water ecosystem components by neutron activation analysis
Published in «Water: chemistry and ecology» № 10 / 2009 , p. 36-40.
Heading: Hydrobiology
Heading: Hydrobiology
Summary:
Biogeneous detritus being formed more than for 7 months in microcosms with Viviparus viviparous, Unio pictorum, Ceratophyllum demersum, contained uranium and thorium. Concentrations of thorium and uranium in such detritus have been firstly changed. The concentration was changed by neutron activation analysis (NAA). New uranium concentrations in biogeneous detritus were 2.1-4.6 mg/kg (dry basis). Obtained data reveal biota’s multifunctional character in water ecosystems.
