As Dr. Waring says in his thoughtful foreword, whether we like or not the "atomic age" is here and atomic energy will no doubt be used for peaceful purposes as well as for war. Injuries are therefore bound to occur even in civilian life, and it behooves doctors to know what to do to fend off the disastrous effects of atomic agents. Dr. Sears has done a fine job of clearly presenting in not too technical language every facet of the subject; certainly everyone seriously interested in industrial practice or civilian defense needs to study carefully and have at hand a manual of this sort, even if at times it makes dreary reading. The book is handy and well printed, and there are many diagrams and photos. Many references to the literature are cited.
