Recent Approach in Radiation Chemistry toward Material and Biological Science

Abstract

In the present Perspective, a recent approach in radiation chemistry is summarized. By employing radiation chemical methods, such as γ-ray radiolysis and pulse radiolysis, powerful oxidative and reductive species can be generated to initiate various reactions. Thus, radiation chemical methods are applicable to various systems in a wide variety of fields and are not restricted to basic radical or radical ion chemistry. For example, our research group has employed radiation chemical methods to elucidate the mechanisms of various phenomena. Here, radiation chemical investigations on the charge delocalization process, excited radical ions, photocatalytic systems, emitting devices, and biological systems are introduced as examples of the wide applicability of radiation chemistry. Radiation chemical methods should be useful for a wide variety of researchers in the future as well.
