X-ray Optics and X-ray Microanalysis covers the proceedings of the Symposium on X-ray Optics and X-ray Microanalysis, held at Stanford University on August 22-24, 1962. The book focuses on X-ray microscopy, microradiography, radiation and irradiation, and X-ray microanalysis. The selection first offers information on the methods of X-ray microscopy and X-ray absorption microanalysis. Discussions focus on X-ray scanning microscopy, contact microradiography, point projection microscopy, and total dry-weight determinations. The text then takes a look at X-ray microanalysis in biology and medicine; electron microscopic enlargements of X-ray absorption micrographs; and automation in microradiography. The publication examines the production of Fresnel zone plates for extreme ultraviolet and soft X radiation; quantitative microradiographic studies of human epidermis; and irradiation effect on total organic nerve-cell material determined by integrating X-ray absorption. The manuscript then reviews the calculation of fluorescence excited by characteristic radiation in the X-ray microanalyzer and the method for calculating the absorption correction in electron-probe microanalysis. The selection is a valuable reference for readers interested in X-ray technology.
