Complexes and Radioprotection

A further aspect to be considered is the interaction of endogenous metals and metalloenzymes with both radiolysis products and extraneous chemicals which may result in radioprotection. Indeed, in any class of compounds there is a reciprocal nature of sensitization and protection that demands that examples exist illustrating both effects. The need for good radioprotectors today, of course, is something which transcends the uses discussed here, given the ever-present threat of radiation damage from nuclear accidents. 

Hydroxyl radical scavenging by species such as DMSO is also a recognized mechanism of protection [96].
