Report produced under Contract W-7401-eng-37 discusses how, during dissolution in nitric acid of Uranium metal which has been irradiated in a pile, Radio-Iodine (8.0 day) and Radio-Xenon (5.3 day) are liberated along with the oxides of nitrogen. Since in the plant these gases are discharged into the atmosphere, the presence of the activities (particularly radio-iodine because of its greater chemical reactivity) presents a physicological hazard. In the summary and conclusions, it is mentioned that under simulated dissolver conditions in the laboratory, the reflux removed a large fraction (70 percent to 90 percent) of the Iodine from the off-gasses.
