Contamination of the atmosphere by radioactive isotopes of iodine constitutes a serious biological hazard and, for this reason, provisions should be made at reactors to prevent such releases in the event of an accident. The efficiency of activated charcoal for adsorption of iodine vapor from air streams was measured by using a radioactive tracer method, and efficiencies of 99.6 to 99.999+% were obtained for various conditions.

Description
Contamination of the atmosphere by radioactive isotopes of iodine constitutes a serious biological hazard and, for this reason, provisions should be made at reactors to prevent such releases in the event of an accident. The efficiency of activated charcoal for adsorption of iodine vapor from air streams was measured by using a radioactive tracer method, and efficiencies of 99.6 to 99.999+% were obtained for various conditions. Comparative tests were run with silver-plated copper ribbon. A criterion for selecting an iodine removal material was developed based on efficiency and resistance to air flow. The iodine vapor adsorption efficiency of a commercial charcoal filter was measured. Various materials were considered for possible application in the emergency exhaust system of the building housing the 5-Mw swimming pool reactor at the Puerto Rico Nuclear Center. Based upon its high adsorption efficiency and retention properties, it is proposed that activated charcoal be utllized for iodine vapor adsorption. (auth)
