The relative efficiency of radicals in radiation damage to deoxyribose.
The radiation damage to Deoxyribose was studied with a view to identify the damaging species. Our results indicate that H, eaq-, CO2- do not cause any appreciable damage in the absence of metal compounds and .OH is the sole damaging entity. Iron compounds sensitize very little O2- damage and CO2- damage could not be sensitized. In N2-saturated solutions metal compounds increase the damage by converting eaq- into deleterious .OH.
