Experiments are described in which iodine-127 and iodine-132 tracer was released as elemental iodine vapor in the DIDO and PLUTO reactor shells to give concentrations in the range 0.01 to 15 mu g/m/sup 3/, and the behavior of the iodine studied over a period of several hours. It was found that most of the iodine disappeared rapidly by deposition on surfaces in the reactor shell and that of the remainder which remained airborne for periods of several hours, part became attached to sub-micron particles in the atmosphere and part appeared to form two iodine compounds. It was found that the release of iodine-127 to the reactor atmosphere could cause the return to the gas phase of radioactive iodine previously deposited on surfaces in the reactor containment vessel. It is suggested that this, in conjunction with an iodine vapor scrubber, may provide an effective method of decontaminating reactor vessels after a release of radioactive iodine. (auth)
