Union Carbide Nuclear Co. vii + 132 pages. Office of Technical Serv­ ices, U. S. Dept. of Commerce, Wash­ ington 25, D. C. 1958. $2.75. This report discusses the radiation accident which occurred at the Y-12 Plant at Oak Ridge, Tennessee, on June 16, 1958. To the extent that informa­ tion is available, it describes the circum­ stances leading to the accident, at­ tempts to reconstruct the nuclear reac­ tivity conditions, and reviews the dosi­ metric means and results which were used to help determine the exposure of affected employees. Included are the findings, conclusions, and recommendations of the 9-man in­ vestigating committee, based on five ex­ hibits which are embodied in the vol­ ume. These exhibits cover the back­ ground of the incident, detailed investi­ gation of the operational evidence, measures taken following the accident, nuclear physics analysis, and dosime­ try. Thirteen appendices are given, along with a glossary of terms and a list of 25 references. The report con­ tains many photographs, diagrams, charts, and tables.

The symposium, held on November 22, 1957, was sponsored by New Eng­ land Nuclear Corp., Atomic Associates, Inc., and Packard Instrument Co. Each of ten speakers described a spe­ cific aspect of tritium methodology. The papers included in the book, while not verbatim transcripts of the respec-



tive talks, were prepared by the au­ thors for publication. Opening remarks by the symposium chairman compare tritium analysis with carbon-14 analysis. This is then fol­ lowed by papers dealing with gas ex­ posure and other methods of labeling; liquid scintillation and gas counting; health physics considerations; uses in pharmaceutical research, reservoir en­ gineering and biochemical studies; and autoradiography with tritium.

The main part of this book has spec­ trograms of a Qual Mix blend having 43 elements and used in qualitative spectrographic analysis in the region, 2000 to 4600 A. Persistent lines of each element are identified, and the Qual Mix spectrum is given in juxtapo­ sition with those of an iron arc and an iron spark. An approximate composition of the Qual Mix blend is given and two sec­ tions are devoted to spectrochemical analysis for trace elements in unknown samples. One deals with cases where the amount of sample is unlimited, and the other discusses treatment of limited samples. In addition to the spectro­ graphic charts, tables show the persist­ ent lines of the 43 elements according to wave length. The Scientific



James R. Irving. 60 pages. Bell­ man Publishing Company, P.O. Box 172, Cambridge 38, Mass. 1958. $1.00. A detailed study is made of scientific investigations by the leading scientists of long ago and their importance in evolving rules for measurement is stressed. Also an outline of studies in astronomy and its mathematical deduc­ tions are given. With the new discov­ eries of the Twentieth Century, new laws changed the study of measure­ ments and then in World War I, when imports were cut off, our production of instruments commenced. The six areas in which they are of importance are listed and the early years of their pro­ ducers are discussed and combinations recorded. With annual sales of $1,165,000,000 and good future prospects, they are now a key industry. A chapter is devoted to uses of in­ struments such as production of medi­ cines, chemicals, light and power, iron and steel, food processing and refrigera­ tion. It is explained that automation is not new, but prediction is that future prospects are better than the current -demand.

NEWS Instrument and Control Engineering.

Lloyd Slater. 46 pages. Bellman Publishing Company, P.O. Box 172, Cambridge 38, Mass. 1958. $1.00. This book discusses instrumentation, its history, and its status today. It states that instrumentation is a field built on many engineering disciplines involving knowledge of mechanics, op­ tics, electronics, and hydraulics. Tech­ nical level of personnel, functional level of personnel, and the six areas in which engineers work are outlined in detail. The three types of work in these areas are discussed. Preparation recommen­ dations for an instrument engineer's career are given, including depth of study and where. Possible diversifica­ tion of study is outlined and employ­ ment opportunities are discussed. The book explains procedure for getting jobs and remuneration to be expected.

pages. Academic Press Inc., I l l Fifth Ave., New York 3, Ν. Υ. 1958. $9.50. These papers provide a survey of techniques available for quality control in process plants and fall into two complementary groups : those covering surveys of the experience gained with control instruments already in use, and those exploring the potential plant ap­ plication of techniques currently in laboratory use only. The publication is divided into six sections as follows : adaptation of labo­ ratory techniques to plant measure­ ment, techniques for gas stream analy­ sis, liquid stream analysis, spectrometric methods, techniques for fluid stream analysis, and measurement of physical properties. The importance of instru­ mentation and automatic control, with its speed, accuracy, quality, and savings in manpower is discussed for the oil, cellulose, metalliferous ores, natural fats, rubber, leather, and food indus­ tries. 62 A

Speed Protein Determination With This LABCONCO Team LABCONCO KJELDAHL APPARATUS


LABCONCO ACID and CAUSTIC DISPENSING UNIT For efficiency in the digestion and distillation phases of protein determination, you can't beat famous Labconco Kjeldahl apparatus. But digestion and distillation are just part of the picture. Adding acid and caustic to your sample and titration are other important steps. Using out-dated methods in the performance of these jobs can be very time consuming, and dangerous . . . if your method involves lifting bottles overhead. With modern Labconco equipment, all solutions can be elevated automatically, all lifting thus eliminated. Why not let us tell you more about the Labconco team for protein determination . . . learn just how much time and work you can save using modern Labconco equipment. Just write . . .

Heffer & Sons, Ltd., Cambridge,. England. 1958. 6 guineas. The Society for Analytical Chemistry, originally The Society of Public Analysts, started publication of The Analyst in 1876. These are the first ten volumes for the years 1876-1885,. republished in facsimile form. During this period, the Society feels, chemical analysis passed to the sphere of an exact science, capable of legal argument and applicable on an industrial scale. The volumes cover the early years of operation of the Sale of Food ancî Drugs Act, 1875, and describe the beginnings of biological examination and the systematizing of water analysis. Then, as now, the journal catered to all classes of analyst.
