Treatment of gas-air flows to remove radioiodine using metallic copper

A procedure was developed for treatment of gas-air flows to remove radioiodine using metallic copper in the temperature range 200–300°C. The compacted product containing CuI and metallic copper is a stable compound which can be used as a matrix for radioiodine disposal. The rates of iodine leaching from this compound, depending on the weight fraction of the incorporated iodine (from 33.3 to 65.3%), vary in the range from 3.0 × 10−8 to 6.6 × 10−8 g cm−2 day−1, respectively.
