The Table of Radioactive Isotopes, published in 1986, is a comprehensive reference for nuclear data. It contains recommended radiation data for all radioactive isotopes, derived from the LBL Isotopes Project's extended Evaluated Nuclear Structure Data File (ENSDF) database. The book includes mass-chain decay schemes updated from the 7th Edition of the Table of Isotopes, tabular data with γ-ray, alpha particle, atomic-electron, beta, and internal bremsstrahlung energies and intensities, and average radiation energies per disintegration. It also includes text and appendices, with the database available to users through the LBL computers. The Table of Radioactive Isotopes is primarily intended for applied users of nuclear data. It includes mass-chain decay schemes, headers with decay modes, mass excess, specific activity, and principal means of production, and photon tables with γ-ray energies and intensities. Alpha particle energies and intensities are also provided, along with beta spectra, internal bremsstrahlung, and particle tables. The data are generally derived from ENSDF with some updating, and uncertainties are calculated for all values. The LBL/ENSDF database, from which the Table of Radioactive Isotopes is produced, contains numerical information of the ENSDF file, Wapstra's 1983 mass table, and data from which the Table of Radioactive Isotopes is produced. The database can be accessed through the DATATRIEVE database management system, which uses simple English-like commands to perform Boolean algebraic searches. Procedures can be written in DATATRIEVE to perform complicated searches and data can be retrieved via VAX/VMS(DCL) procedures and processed by Fortran programs. A library of interactive programs is available to calculate internal conversion coefficients, atomic electron spectra, x-ray and Auger-electron yields, average energies, and level scheme balances. The database is available on the LBL VAX-8600 computer cluster and can be accessed via direct dial-up, DECnet, MILNET, and TYMNET networks. The database can be searched using the DATATRIEVE database management system, which uses simple English-like commands and Boolean algebra to search the data. The LBL/ENSDF database is supported by the U.S. Department of Energy and is available for use by prospective users who are encouraged to contact the Isotopes Project for further information.The Table of Radioactive Isotopes, published in 1986, is a comprehensive reference for nuclear data.
