Richard E. Faw Englewood Assessment: Sources and Exposures and J. Kenneth Shultis Cliffs, NJ: Prentice-Hall, Inc, 1993. Cloth, $70.00; pp 681; 340 figures and tables. In this book, the authors have attempted to define the discipline that they term radiologic assessment. As stated in the preface, the book does not deal with the topics of operational radiation safety or nuclear measurements. Instead, it deals with evaluation of radiation doses to individuals and population groups from radiation sources, the characterization of radiation sources, and the dispersal of radioactive materials in the environment. This text appears to be aimed at the professional working in any one of the many diverse fields of radiation protection and risk analysis. Its historical perspective and the problems given at the end of each chapter make it a candidate for an in-depth graduatelevel radiation protection text. While the level of the book is suitable for radiologists, it is not particularly well suited for when one is looking for current standards. The text is generally well written, although it is not intended for light reading, as indicated by the liberal use of technologists or medical students. After the introductory chapter, which outlines the historical evolution of radiation protection standards, and a chapter on the basic physics of interaction of ionizing radiation with matter, chapters 3-5 cover biologic effects and sources of exposure, both natural and artificial. Chapters 6 and 7 discuss shielding concepts for gamma rays, neutrons, and electrons. A good presentation of internal dose evaluation is contained in chapter 8. Chapters 9-1 1 discuss dispersion of radionuclides in the environment and pathway modeling. The discussion of historically important works on radiation protection standards, extending from International Commission on Radiological Protection (ICRP) publication 2 (1960) up to the Biological Effects of Ionizing Radiation (BEIR) V report (1990), can be confusing tables and equations. Perhaps in an attempt to force the reader to become adept at converting between SI and traditional units of radioactivity and exposure, the authors have chosen to use both, with preference given to SI units. The problems provided at the end of each chapter cover the entire spectrum of radiologic assessment, with applications strictly to radiology in the minority. Since no answers are provided for the problems, the examples in the text are very useful. Only chapter 8 explicitly includes examples, while chapter 4 provides sample calculations. Other examples appear scattered throughout the text. X-ray shielding from the perspective of the medical physicist is only briefly discussed, with reference to National Council on Radiation Protection and Measurements (NCRP) report 49 (1976) and related works. The authors have done a commendable job of bringing a wide variety of basic science topics in radiation protechon together into a coherent text. While not particularly aimed at physicists in radiology, the basic concepts presented are applicable to their work and provide insight into the problems faced by their colleagues in other areas of radiologic assessment. throughout pendi.xes, The large number of tables the text, as well as the apmake this a useful reference for a wide range of practical calculations.
