Physical Processes in Radiation Biology covers the proceedings of an International Symposium on Physical Processes in Radiation Biology, held at the Kellogg Center for Continuing Education, Michigan State University on May 6-8, 1963, sponsored by the U.S. Atomic Energy Commission. The symposium aims to address the core problems of radiation biology concerning the absorption, distribution, and utilization of high energy packets in biological systems. This book is composed of 21 chapters, and begins with an introduction to the absorption, excitation, and transfer processes in molecular solids. The subsequent chapters discuss the nature of exciton processes; the mechanisms of charge transport in biological materials; the interactions of fast and slow electrons with model systems; the importance of liquid structures in determining the development of radiation damage; and the nature of the metastable species formed. The concluding chapters explore the importance of charge migration in energy transfer processes in different biological systems and the significance of higher excited levels in charge migration and energy transfer. These chapters also describe the nature of the hydration of electrons and protons in aqueous systems. This book will be of great value to radiation biologists, biophysicists, physical chemists, and physicists.

Advances in Radiation Biology, Volume 1, provides an overview of the state of knowledge in radiation biology. The book contains six chapters and opens with a review some of the recent work bearing on the nature of the radicals produced in water and on the rates of some of the reactions of the radicals. It also comments on some of the applications of the radical model which have been made. These are followed by a chapter on the process of photosynthesis, covering light absorption and emission by pigments, electromagnetic energy transfer among and between pigment molecules, and the (physical) transfer and migration of electronic charge. Subsequent chapters deal with the effects of tritium irradiation on cells; the effects of small doses of ionizing radiation; the radiation chemical reactions of the amino acids; and the nature of temperature effects on enzyme inactivation by various radiations.

Advances in Radiation Biology, Volume 2, reflects a continuing effort to provide wide-ranging analyses of progress in various phases of radiation research. The articles cover a spectrum of topics varying from the initial physical events which allow us to discriminate color, to the chemical and biological processes which determine the extent and permanence of radiation damage, and finally to the role of genetic control and damage in determining the fate of irradiated cells. The basic emphasis of the articles also varies. In some, the main attempt is to review extensively the available data so as to evaluate the possible contributions of various mechanisms to a given phenomenon. One article is devoted an evaluation of one physical approach which appears to be a promising way of understanding color perception. These different treatments should be of value not only to the researcher but also to the student, inasmuch as each approach is invariably dictated by the state of the art in the area being covered.

Advances in Radiation Biology, Volume 3, reflects a continuing effort to cover a wide spectrum of radiation science in this serial publication. The book contains six chapters and opens with a review of developments of physical theory in an area of interest to biophysicists. This is followed by subsequent chapters on problem of photodynamic action, which demonstrates the role of energy transfer in radiation damage development; the sensitization of biological systems by small molecules; and problems concerned with the identification and study of the biological effects of radioactive decay. Subsequent chapters deal with a survey of human radiation cytogenetics and progress in human radiobiology.
