Abstract
Maximum attainable self-absorption dose for cemented composite ion-exc hanger, consisting of nickel hexacyanoferrate and polyacrylonitrile bi nding matrix loaded with Cs-137 up to repository acceptable level (1.1 10(12) Bq . m(-3)) was calculated to be similar to 10(5) Gy. The ceme nted absorber with sorbed caesium was irradiated by Co-60 source UP to 1 MGy, and leach tests were performed to determine possible influence of self-irradiation on the caesium leachability. No radiation induced changes in caesium immobilisation in solidified ion-exchanger were ob served.
