COMPOSITE ABSORBERS OF INORGANIC ION-EXCHANGERS AND POLYACRYLONITRILEBINDING MATRIX - V - INFLUENCE OF IONIZING-RADIATION ON THE LEACHABILITY OF CS-137 FROM CEMENTED COMPOSITE NIFC-PAN ABSORBER
A. Motl et al., COMPOSITE ABSORBERS OF INORGANIC ION-EXCHANGERS AND POLYACRYLONITRILEBINDING MATRIX - V - INFLUENCE OF IONIZING-RADIATION ON THE LEACHABILITY OF CS-137 FROM CEMENTED COMPOSITE NIFC-PAN ABSORBER, Journal of radioanalytical and nuclear chemistry, 222(1-2), 1997, pp. 205-207
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.
