Download or read book Measurement Of Weak Radioactivity written by Pall Theodorsson and published by World Scientific. This book was released on 1996-12-11 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended for scientists engaged in the measurement of weak alpha, beta, and gamma active samples; in health physics, environmental control, nuclear geophysics, tracer work, radiocarbon dating etc. It describes the underlying principles of radiation measurement and the detectors used. It also covers the sources of background, analyzes their effect on the detector and discusses economic ways to reduce the background. The most important types of low-level counting systems and the measurement of some of the more important radioisotopes are described here. In cases where more than one type can be used, the selection of the most suitable system is shown.
