Modern Trends in Physiological Sciences, Volume 7: Radiation Protection and Recovery covers the biological, physiological, and biochemical methods created to protect living organisms from radiation damage. This book is composed of 12 chapters that evaluate the methods of protecting macromolecules in vitro against ionizing radiation damage. It addresses the degradation of polymethacrylic acid and the polymerization of vinyl monomers. Some of the topics covered in the book are the chemical protection to mammals against ionizing radiation; chemical protective agents; methods of protection and recovery in bacteria and fungi; and effect of cultural conditions and physiological state on radiosensitivity. Other chapters deal with the experimental modification of radiosensitivity and the role of phase state in inactivitation. These topics are followed by an analysis of the effect of the gaseous environment during irradiation. The chemical protection against inactivation and mutation is also presented. The last chapter is devoted to the environmental factors in radioresistance. The book can provide useful information to doctors, radiologists, students, and researchers.
