Destruction of genotoxic wastes mixed with radioactive products.
Before their disposal, genotoxic substances are destroyed by strong oxidizing agents. If there are molecules labelled with radionuclides in the medium which is oxidized, then this treatment may bring about the release of gaseous radioactive compounds. We have looked for evidence of such a release following the action of K permanganate and sodium hypochlorite on molecules labelled with 3H, 14C, 32P, and 125I. Among the compounds examined, only those labelled with 14C showed significant quantities of radioactive gas released, with values up to 60% of the total radioactivity. For the other products, less than 0.6% of the radioactivity appeared in a volatile form.
