Radiolytic oxidation of technetium dioxide
Description
Samples of the insoluble technetium dioxide (99TcO2) were slurried in distilled water and in seawater and allowed to oxidize under the influence of their own radiation (0.293 keV B-). Under these conditions only about 10 to 15% of the Tc was oxidized. When the technetium solutions were subjected to greater radiation fields by addition of 244Cm the oxidation of the technetium to pertechnetate was virtually complete. In the case of TcO2 slurries without added radioactivity it was found that the concentration of pertechnetate ion, TcO4, reached a maximum and then declined to about one-half of that maximum value
