1983-1-1 · Sorption of 103 and 104 by iron oxides is potentially useful for disposal of radioactive I-129 produced by nuclear reactors. Iodine may be disposed of in the 103 - form, I- may be oxidized to iodate by oxygen, or I0; and IO4 may be formed as results of radiolysis. The use of iron oxide as a backfill material has been suggested elsewhere (19).
