Tables for the Energy and Photon Distribution in Equilibrium Radiation Spectra covers a collection of tables used for calculating the energy and photon distribution in equilibrium radiation. The book discusses the main characteristics of radiation; the equilibrium between radiation and matter using Kirchhoff's laws; the energy and photon distribution in the spectrum of equilibrium radiation; and the energy and photon distribution of equilibrium radiation over finite frequency intervals. The text then describes heat radiation emitted by real bodies; heat radiation in the space between bodies at different temperatures or in a medium in the absence of total thermodynamic equilibrium; the use of thermal radiation for investigating the properties of a substance; and optical pyrometry. Tables for each of the above mentioned topics are illustrated. Each table is preceded by a description and rules for using it in practical calculations. Numerical values of the conversion coefficients for the different spectral scales and for conversion from densities to fluxes are also given. Those involved in physics, illumination and heat engineering, meteorology, and astrophysics will find the book useful.

The need has arisen for a comprehensive handbook for engineers faced with problems of radiation shielding design. Although there are several excellent books on shielding, they either do not give enough consideration to the many practical design problems, or are limited to special aspects of the subject. Recognizing the universal need, the International Atomic Energy Agency decided to sponsor the publication ofthe present Engineering Compendium on Radiation Shield ing. At the first editorial discussions it was agreed that, if such a book were to be undertaken, it would be appropriate not only to create a useful design tool for the practising engineer but also to include well-referenced basic data for the research worker. Although trying to keep the book down to a reasonable size, the editors have aimed at a complete presentation of the subject, covering and linking both the tech nology and the science of shielding. Efforts to make terms and definitions consistent throughout have been only partially successful, owing to the continuing development of new ideas. However, inconsisten cies that could not be eliminated are identified whenever possible.
