Dr. Schweitzer and Dr. Whitney have written a basic laboratory textbook on the use of radioactive materials in research. Although the book is, as the title states, written as a manual of tracer technics, it contains much useful material for workers in any field where radioactive materials are used. It should prove to be an excellent laboratory manual for a short course used to train students and technical personnel for work in laboratories using radioactive materials. It must, however, be supplemented by a good theoretic textbook in the field or by a course of lectures explaining the theory involved.
The first four chapters stress proper handling of radioactive materials, from the viewpoint of both protection of personnel and maintenance of optimum reliability of results. Radioactive hazards, decontamination, protection measures, room arrangements, equipment and experimental methods are discussed in detail by persons who are familiar with the problems encountered at the
