This volume is the English translation of the 3rd German edition of Die technisehen Anwendungen der Radioaktivitat, Band I with amendments. The first edition, published in 1956, was heavily indebted to the 19.55 Geneva "Atoms for Peace" Conference and represented one of the first surveys in the industrial applieat,ions field. The seoond German edition was published in 1957 with the third edition appearing in 11162. The English t,ranslation was copyrighted in 1966. The third edition relied heavily on the 1958 Geneva Conference paper? along with those from a Paris Couference in 1957 and a Copenhagen Conference in 1060. The first 70 pages are devoted t o a aurvey of fundamentals of radioacbivity and measurement. This is followed by about 40 pages of applications to chemioal analysis. The remaining 220 pages sketch in a hurried fashion a very broad spectrum of applications to industry with emphasis on field or in-plant. uses. The chapter headings include mining and oil pmduction, metallurgical, engineering, and elec-
