A convenient source of radiation data which incorporates the changes dictated by present-day science and computer technology, presented with a high degree of uniformity, completeness, and consistency in both the data and appendices. Includes tables of adopted properties for all radiations emitted by nuclei, which were derived from experimental data plus reliable calculations, along with adopted properties based on statistical analyses of existing experimental data alone. Other derived adopted properties (e.g. average photon energies per disintegration) are calculated when strong user demand is anticipated. Over 260 drawings accompany the text.
