Advances in Biological and Medical Physics, Volume VIII is a collection of papers that deals with chemical elements of blood, neutron activation analysis, and low level gamma-ray scintillation spectrometry. One paper describes the analysis of a large number of chemical elements in a single sample of human blood serum that includes the mean values gathered for 66 chemical elements. Another paper reviews the application of neutron activation analysis to biological and medical research, particularly in the detection and quantitation of trace elements in biological tissues. Some papers discuss the use of heavy ions in molecular and cellular radiobiology, the physics of space radiation, and carcinogenesis mechanisms. One paper discusses the radio-biological consequences of the ionizing radiation on a biological system that depends on the spatial distribution of the energy the system absorbs. The paper notes that the efficiency of heavy ions to inactivate dried enzymes kept at various constant temperatures during the exposure differs significantly from results obtained from that of sparsely ionizing radiations. Results gathered from comparisons of model and experiments, show that indirect energy transfers, such as those made by intermediary free radicals or other secondary reaction products, can play a role in carcinogenesis. The collection can prove beneficial for biochemists, micro-biologists, cellular researchers, and academicians involved in medical physics, radiological physics, or in the study of cellular biology and oncology.

Space Radiation Biology and Related Topics provides information pertinent to the fundamental aspects of space radiation biology. This book discusses space radiation hazards as well as the importance of natural radiations in the processes of biogenesis. Organized into 12 chapters, this book begins with an overview of the fundamental aspects of radiobiology. This text then discusses the theoretical treatments of the chronic radiation response and the applicability of some of its features in extended manned space missions. Other chapters review the literature on models for recovery from radiation damage to some cellular systems. This book discusses as well the effects of radiations on mammals, with emphasis on those effects pertinent to the space-flight situation. The final chapter deals with the safety of nuclear power in space and explains the three types of nuclear devices designed for power production in space. This book is a valuable resource for radiologists, radiobiologists, and radiotherapists.

Advances in Biological and Medical Physics, Volume VI, provides an overview of the state of knowledge in biological and medical physics. The book opens with a study on ion and water transport in stomach and intestine. This is followed by separate chapters on artificial and induced periodicity in living cells; radiobiological aspects of the induction of lysogenic bacteria to produce phage with x-ray, gamma ray, and ultraviolet radiations; cell studies with microspectrography; and the effect of ionizing radiation on tumors in experimental animals. Subsequent chapters deal with biological effects of fallout from nuclear weapons tests; radiological contrast enhancing methods; measurement of regional circulation in the central nervous system by the use of radioactive inert gas; and intense ultrasound in investigations of the central nervous system. Also covered are the use of isotopic tracers in the study of diabetes; application of light scattering to biological systems; and physical and chemical mechanisms in the injury of cells by ionizing radiations.

Advances in Biological and Medical Physics, Volume IV, provides an overview of the state of knowledge in biological and medical physics. The book contains eight chapters and opens with a discussion of the application of X-ray diffraction to crystalline proteins. This is followed by separate chapters on the relationship between the chemical information which can be stored in the nucleic acid molecule and the sequence of amino acids found in polypeptides and proteins; materials for the biophysical and biochemical study of cell division; and the action of high and low temperatures in the destruction of unicellular organisms. Subsequent chapters deal with infrared spectrometry; the kinetics of iron metabolism; the gross composition of the body; and an argument for a theory of aging, which states that the tendency toward further disease experience is at a metabolic rate determined by accumulated disease experience of the past.

Advances in Biological and Medical Physics, Volume V, provides an overview of the state of knowledge in biological and medical physics. The book opens with a discussion of electron spin resonance and nuclear magnetic resonance and their applications to biology. This is followed by separate chapters on action spectroscopy, the genetics of somatic mammalian cells, partial-cell irradiation, electrical properties of tissue and cell suspensions, quantum effects in human vision, and television techniques in biology and medicine. Subsequent chapters deal with studies on the use of antibodies as carriers of radioactivity for therapy; studies on the fundamentals of cholesterol metabolism performed with cholesterol labeled with tritium; examples of low level counting problems which have been successfully solved; and the radioactivity of the human body.
