Chemical and mineral composition of uranium-containing ores from the Srednyaya Padma field (Karelia) was studied to forecast radioecological consequences of commercial production of vanadium at mining of fields with uranium mineralization. Along with carnotite, tyuyamunite, and pitchblendes of...

Twelve most intensive hard X-ray emission lines belonging to two multiplets (2p-3d and 2p-4d) and three doublets (2s-3p, 2s-4p, and 2p-3s) of the uranium L-series were studied by using a precise crystal-diffraction X-ray spectrometer. Chemical shift (CS) values were obtained for the first time...

Chemical shifts (ChSh) of nine emission lines of the uranium L-series in uranium oxides UO2+x (x=0-1) with respect to UO2 were studied by using a precise crystal-diffraction X-ray spectrometer. ChSh of Lα1,α2 uranium and thorium lines in solid solutions yUO2·(1-y )ThO2 (y=0:1) were measured...
