Frolov, N. Andreychuk, K. Rotmanov, L. Frolova, V. Vasiliev] This paper presents the results of systematic kinetic studies of valence transformation of U, Np, Pu, Am and Bk in nitrate- and perchlorate solutions under the effect of intensive internal alpha-radiation emitted by244Cm nuclides. The high dose rate of solutions (D=1-8 Gy/s) provides a sufficient yield of H2O2, HNO2 and ClO2 — the main products of alpharadiolysis of water, nitrate and perchlorate ions, respectively, which was determined by spectrophotometric methods immediately in the course of the process under study. To describe the results, a kinetic scheme considering the effect of dose rate and solution composition is proposed. The calculations have been carried out on a BESM-6 computer, a satisfactory agreement between the calculated and experimental data has been obtained. Akadémiai Kiadó, 1990 Frolov A.
