In the γ-radiolysis of carbon dioxide, the back reaction or reoxidation of carbon monoxide, proceeds at a moderate rate with propane concentration less than 0.5%, reducing the apparent <I>G</I>(CO) value. Concerning the total pressure and dose rate dependence of the <I>G</I>(CO) value with such small propane addition, it was found that the back reaction was accelerated by raising the total pressure and by lowering the dose rate. The following reactions of clustered negative ions are considered to explain the pressure and dose rate effects:<BR>X<SUP>−</SUP>+CO→CO<SUB>2</SUB>+Y<SUP>−</SUP>+Z<SUB>1</SUB>,<BR>X<SUP>−</SUP>+C<SUB>3</SUB>H<SUB>8</SUB>→Y<SUP>−</SUP>+Z<SUB>2</SUB>,<BR>X<SUP>−</SUP>+X<SUP>+</SUP>→<I>m</I>CO<SUB>2</SUB>+Z<SUB>3</SUB>,<BR>where X<SUP>−</SUP> stands for a clustered negative ion.
