Fig. 2: G-values and % molar yields for acetol and solketal from glycerol mixtures.

After 50 kGy irradiations of binary aqueous and ternary glycerol mixtures. a G-values for only γ-ray irradiations with an average dose rate of 40 Gy min⁻¹. b G-values for mixed-field neutron+γ-ray irradiations with a dose rate of 3260 Gy min⁻¹. c % molar yields for only γ-ray irradiations. d % molar yields of mixed-field and unirradiated control samples. The indicated ternary mixtures containing glycerol, acetone and water have the following compositions in mol.%: (i) 20, 20, 60; (ii) 13, 21, 65; and (iii) 11, 32, 56, respectively. (See Supplementary Table 5 for data.) G-value error bars represent the combination of errors from the RSD% of analyte concentration curves and absorbed dose uncertainties for each sample. %Molar yield errors derive only from the RSD% of analyte concentration curves for each sample. Reference data from Baugh et al.: (Ref)²⁹, for acetol used in (a), used N₂O-saturated aqueous glycerol samples with a γ-ray dose and dose rate of 1.4 kGy and 8 Gy min⁻¹, respectively.
