✦ Synopsis

The effect of CO on the y-radiation induced reaction between graphite and CO, has been investigated at 225-375°C. G(-C) values have been determined using a r4C-labelled PGA graphite specimen for a range of CO concentrations from 10 vpm to 1.3 per cent. The results agree with those of other workers in areas of overlap and fit a previous mechanism for CO inhibition. Equations for the dependence of G(--C) on CO concentrations at 375, 280 and 225°C are derived. The product ratio '*CO: 14C:0.L is not significantly affected by CO concentration, but increases with temperature. The mechanism of the radioiytic gasification of graphite by CO, is discussed in the light of these results.
