686. Radiolysis of carbon dioxide

Abstract

The radiolysis of carbon dioxide in the presence of sulfur dioxide and nitrogen dioxide as scavengers was studied by using the Harwell nuclear reactor, BEPO, and two different sources of gamma radiation. The measured G value for carbon monoxide production is 3.51 plus or minus 0.23 for gamma radiation. Possible reasons for the discrepancy between this value and previous data are discussed. Uncertainties in the methods of dosimetry used ior reactor radiation are discussed and it is concluded that G(CO) ior reactor radiation agrees with the value for gamma radiation within the limits of these uncertainties.
