Description
A series of two irradiation experiments at -30°C were performed on CCl3F using a 282 Ci 85Kr source, with the irradiation facility arranged in (a) and (b) in flow modes of operation, to determine the decomposition yields in relation to absorbed dose, and to observe differences in the CCl3F decomposition behavior according to combination of radiation source and operating mode. The experiments revealed-among other data-that : (1) The decomposition yield of CCl3F and the yields of the individual degradation products were related linearly to the absorbed dose, with coefficients representing CCl3F energy decomposition of 0.026mol/o/Mrad (G=3.2) in batch and 0.053mol/o/Mrad (G=6.7) in flow system ; (2) No significant difference in the decomposition yield was observed between irradiation by 85Kr β-rays and 60Co γ-rays ; (3) Compared with batch, flow operation was found to provide higher CC13F decomposition yield ; (4) Inspection of the inner surfaces of the circuit upon disassembly of the facility after the experiment revealed no corrosion or deposit ; (5) In an actual industrial 85Kr removal plant, the G-value for CCl3F decomposition is expected to amount to about 10, so that the radiation damage of fluorocarbon should not present a critical problem for the solvent absorption process.
