FOREWORD The Subcommittee on Radiochemistry is one of a number of subcommittees working under the Committee on Nuclear Science within the National Academy of Sciences - National Research Council. Its members represent government, industrial, and university laboratories in the areas of radlochemistry and nuclear chemistry. Support for the activities of this and other subcommittees of the Committee on Nuclear Science is provided by a grant from the National Science Foundation. The subcommittee has concerned itself with preparation of publications, encouraging and supporting activities in nuclear education,sponsoring symposia on selected current topics in radiochemistry and nuclear chemistry, and investigating special problems as they arise. A series of monographs on the radio- chemistry of essentially all the elements and on radiochemical techniques is being published. Initiation and encouragement of publication of articles on nuclear education in various subject areas of chemistry have occurred, and development and improvement of certain education activities (e.g., laboratory and demonstration experiments with radioactivity) have been encouraged and assisted. Radioactive contamination of reagents and materials has been investigated and specific recommendations made. This series of monographs has resulted from the need for comprehensive compilations of radiochemical and nuclear chemical information. Each monograph collects in one volume the pertinent information required for radiochemical work with an individual element or with a specialized technique. The U. S. Atomic Energy Commission has sponsored the printing of the series. Comments and suggestions for further publications and activi- ties of value to persons working with radioactivity are welcomed by the Subcommittee. N. E. Ballou, Chairman Subcommittee on Radiochemistry ill
Preface to the revised edition A considerable number of papers have appeared in the literature on the radiochemistry and chemistry of arsenic since the first edition of the monograph was published. The general form and much of the original content of the monograph has been retained, substantial additions being made where necessary. The reviser would like to thank Mr. R. W. C1arke, Information Officer of the Chemistry Division, A.E.R.E., for his great help in conducting a very thorough literature search. iv
