Request a sales quoteFundamentals of Radiobiology presents a clear picture of the effects of radiation to living organisms. It discusses the steps leading from the absorption of energy to death or final injury. The focus of study is the changes induced at the molecular level by absorbing energy. Some of the topics covered in the book are the methods for determining the direct and indirect action in biological systems, the nature of the initial chemical lesion in cellular radiobiology, the definition of target theory and the meaning of poison theory. The subjects on general radiation chemistry are also covered. The fields of radiation chemistry that will be discussed are the role of excitation, the variation of reactions between gases, liquids, and solids; and the status of free radicals created. The effects of radiation on macromolecules are discussed. The text defines the important role of metabolism in the development of the lesions. An analysis of the interactions of ionizing radiations with is presented. A chapter of the volume is devoted to the radiation chemistry of aqueous systems. Another section of the book focuses on the chemicals which simulate the biological effects of ionizing radiations. The book will provide useful information to doctors, chemists, biologists, radiologists, students and researchers.

Peter Alexander
Peter Alexander is a senior lecturer at University of Edinburgh jointly between the School of Geosciences and the Global Academy of Agriculture and Food Security.
Peter’s research aims to better understand the socio-economic and environmental interactions and trade-offs associated with the global food system. Approaches use high-performance computing to apply data and computationally intensive techniques, such as agent-based modelling, to explore the complex interactions inherent with the system. Work has included developing a new global agricultural land use model (LandSyMM) integrated with an ecosystem model to represent the two-way and spatially specific interactions and trade flows. Interests include how changes in food consumption and preferences, e.g., dietary shifts, impact environmental outcomes such as biodiversity loss and climate regulation. He is the principal investigator on the Resilience of the UK food system to Global Shocks project (RUGS).
