Nuclear transmutation is under consideration as a disposal method, primarily for Tc-99 and I-129 as these both represent the greatest biohazards and have the greatest neutron capture cross sections, although transmutation is still slow compared to fission of actinides in a reactor. Transmutation has also been considered for Cs-135, but is almost certainly not worthwhile for the other LLFPs. Given that stable Caesium-133 is also produced in nuclear fission and both it and its neutron activation product Cs are neutron poisons, transmutation of Cs might necessitate isotope separation. Tc is particularly attractive for transmutation not only due to the undesirable properties of the product to be destroyed and the relatively high neutron absorption cross section but also because Tc rapidly beta decays to stable Ru. Ruthenium has no radioactive isotopes with half lives much longer than a year and the price of ruthenium is relatively high, making the destruction of Tc into a potentially lucrative source of producing a precious metal from an undesirable feedstock.
