This book illustrates the role of photoprotective and radioprotective metabolites from natural sources. Various classes of radioprotective metabolites derived from cyanobacteria, algae, fungi, bryophytes, pteridophytes, gymnosperms, and higher plants have been explained to reinforce the current knowledge in this field. In addition, the book elucidates the potential applications of these metabolites in pharmaceutics, cosmetics, and biomedical sciences that will help develop commercial products in modern anti-radiation therapeutics. Topics such as stress tolerance environmental strategies, evolutionary tendency, and biosynthetic route of radioprotective compounds for cost-effective large-scale industrial production of the metabolites are also covered in the book. This book will add to the understanding of radioprotective mechanisms and curative measures for various deleterious diseases leading to cancer development. This volume also offers the latest insights into current and upcoming issues that arise from solar and atomic radiations and their amelioration by inherent radioprotective mechanisms of green plants. This book benefits readers from academia, industry, colleges, and research students to better understand the impacts of various radiations and the development of radioprotective green compounds.
