By Floyd F. Momyer, Jr, the October 1960 publication  is one in a series monographs on radiochemistry of the elements prepared by the Subcommittee on Radiochemistry working under the Committee on Nuclear Science within the National Academy of Sciences--National Research Council. There is included a review of the nuclear and chmical features of particular interest to the radiochemist, a discussion of problems of dissolution of a sample and counting techniqes, and finally, a collection of radiochemical proceures for the element as found in the literature. The early sections of the monograph are devoted to general reviews of the rare gas properties of interst to the radiochemist and to some general dicussion ofseparation techniques for rare gases.  The last three chapter are respectively a dicussion ofthe removal of rare gases from targets, a dicussion of techniques used for counting radiocactive rare gases, and a collection of radiochemical procedures for rare gases.
