BARKER, R.

In a general study of the radiolysis of liquid acetone, it was found that the yields of products are affected both by the linear energy transfer of the radiation and also the dose rate. The G value for carbon monoxide production was found to decrease with increasing dose rate. The variation of the product ratios with dose rate are explained in terms of competing reactions and the overlapping of diffused spurs at higher dose rates. Comparison of the results of gamma and proton irradiation illustrates markedly the effect of dose rate and linear energy transfer on the products of the radiolysis of acetone. G_CH3 (total) for gamma irradiation is equal to 2.47 plus or minus 0.25, compared with G_CH3 (total) equal to 2.24 plus or minus 0.25 for proton irradiations. Scavenging experiments (with iodine) showed that at low dose rates at least half of the yield of methyl ethyl ketone was unaffected.
