A mathematical model of the radiation-chemical behavior of neptunium is presented for a wide range of {alpha}-and {gamma}-irradiation doses. Equations determining the equilibrium concentrations of NP(IV), Np(V), and Np(VI) are derived for various concentrations of HNO{sub 3} and dose rates of the ionizing irradiation. The rate constants of the reactions NP(IV) + OH, Np(IV) + NO{sub 3}, Np(V) + NO{sub 2}, Np(V) + H, Np(IV), and Np(V) + Np(V) are obtained by the mathematical modeling.
