Radiation-chemical oxidation of neptunium in perchloric acid solutions
Description
The γ-radiation effect (at a dose rate of 5x1016 eV/mlxs) on 1x10-3 Np(6) and Np(5) perchloric acid solutions is studied. The output of Np(6) loss in aerated 0.001-0.005M HClO4 solutions was 2.4 ions/100 eV. The output of Np(5) loss in solutions saturated with nitrous oxide was 2.1 ions/100 eV at pH-4. In aerated 0.1-1.0 M HClO4 solutions in presence of XeO4 the output of Np(5) loss grows from 6.6 to 13.5 ions/100 eV as (XeO3)0 increases from 1x10-3 to 2x10-2 M. Possible process mechanisms have been proposed
