Reductive dissolution of neutron- and gamma-irradiated magnetite

The influence of reactor (γ + n) preirradiation on the dissolution of magnetite microcrystals synthetized by a low-temperature wet method was studied. The solvent used was an acid aqueous solution of ascorbic acid. Neither the mechanism of reaction nor the nature of the reactive sites is changed by...
