The book "Radioisotopes and Life Processes (Revised)" by Renato Bazerga and Walter Kisielski is a well-known study in the field of the use of radioisotopes in life processes. In this book, the authors carefully consider the effects of radioactive elements on organisms, metabolic processes, and biological systems. The publication has been revised and updated taking into account the latest research in the field. This book will be a useful source of information for scientists interested in the interaction of radioisotopes with living nature and their influence on life processes.
