The Toxicology of Radioactive Substances, Volume 3: Iron-59 deals with the experimental results of tests conducted at the Radiotoxicology Laboratory of the Institute of Occupational Hygiene and Disease, Academy of Medical Sciences, U.S.S.R. The book focuses on studies made on iron-59, which is widely used in science and technology, such as in the metal industry and in the research of hemoglobin metabolism in the bone marrow and red cells. Other studies show, however, that there is a long-term detrimental effect of intake of iron-59. The text then gives a brief outline of the physical, chemical, and biological properties of iron. Research also shows that the body's reaction to radioactive substances depends on how these are transmitted to the body and on their physicochemical properties. The effect of prolonged administration of radioactive iron on the electrical activity of the cerebral cortex of animals is analyzed, of which, possibly, the nervous system is most affected. The book notes also the changes in the red blood cells during chronic administration of iron-59 in small doses, wherein the hemoglobin levels increased temporarily. Studies of prolonged exposure to radioactive isotopes during pregnancy of the test animals show that there are significant changes in erythropoiesis, associated with iron deficiency. In another study, the prolonged internal administration of radioactive substances showed phasic changes in the height of electrocardiographic waves of the test animals. The text is suitable for physicists, nuclear scientists, doctors of toxicology, and researchers in nuclear medicine.

Experts have stated that the conviction of the innocent is more often caused by erroneous identification than by any other single factor. The author probes the subject in depth, pointing out the danger of this type of evidence and analyzing police practices which contribute to the danger. He shows how those procedures could be improved and explains the relationship between certain rules of evidence and the identification problem. He suggests rules of criminal procedure and evidence which would go a long way toward alleviating the problem. Over 150 American cases as well as cases from such fore.

Occupational Health Practice is a comprehensive account of the practice of protecting and improving the health of people at work, with some emphasis on the special needs of workers in developing countries. Topics covered by this book include the functions of an occupational health service; special examinations in occupational medicine; uses and methods of epidemiology; and ergonomics. The mental health of people at work, prevention of occupational disease, and ethics in occupational health practice are also discussed. This book is comprised of 22 chapters and begins by outlining national developments in occupational medicine, along with the different forms of service provided by private enterprise and the state. The factors that influence a nation or an industrial organization to pay attention to the health of people at work are also considered. The discussion then turns to the importance of health to one's work, the functions of an occupational health service, and prevention of accidents and occupational disease. Methods used in the study of groups of workers are described in sections on epidemiology, field surveys, and the collection and handling of sickness absence data. The text also looks at ergonomics, occupational hygiene, and ethics and education in occupational health. This monograph will be useful to physicians, hygienists, nurses, and safety officers working in the field of occupational health; to those whose interests encompass occupational health, but cannot attend a course; and to medical and non-medical specialists in related fields.
