Abstract
The chemical effects of the isomeric transitions of 127mTe and 129mTe have been investigated in solid ammonium and potassium halo-tellurates (IV), tellurium dioxide, and tellurous acid, and also in aqueous solutions of telluric acid containing halide ions. Almost no daughter nuclides were found in the tellurium (VI) fraction in the case of solid halo-complex salts, tellurium dioxide, and tellurous acid. For aqueous solutions and ammonium fluoride solutions of telluric acid, however, 60-70% of the daughter nuclides were found in the tellurium (IV) fraction after the isomeric transition. In the other solutions, more than 90% of the daughter nuclides were found in the tellurium- (IV) fraction.
