ZZ DRALIST, Radioactive Decay Data for Dosimetry and Hazard Assessment

1 - Description of program or function: Format: DLC-46/MEDLIST output format and in an abbreviated form. Nuclides: 561; Origin: Evaluated Nuclear Data Structure Fil (ENSDF). DRALIST is a data set of radioactive decay energies, spectra, half lives, and other information for 561 radionuclides in DLC-46/MEDLIST output format and also in an abbreviated form. The data are derived from the Evaluated Nuclear Data Structure File (ENSDF) using the MEDLIST program. A modified version of the MEDPRINT program with improved editing capability plus a file of decay branching information are provided. 2 - Method of solution: The radioactive decay data tabulated for the report result from the continual expansion and updating of the data base published in ORNL/NUREG/TM-102. In addition to the radionuclides of interest in the nuclear fuel cycle, the data base comprises most of the nuclides occurring naturally in the environment, those of current interest in nuclear medicine and fusion reactor technology, and some additional radionuclides of use in the estimation of annual limits of intake and derived air concentrations for accupationally exposed individuals. The current data base contains approximately 500 radionuclides
