Abstract

The radiation damage to Deoxyribose was studied with a view to identify the damaging species. Our results indicate that H, e−, 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-darnage could not be sensitized. In N2-saturated solutions metal compounds increase the damage by converting e− into deleterious OH.
