The recommended k factors for 81 -lines of 24 elements, which are useful for neutron induced prompt -ray analysis (PGA) and are not influenced by neutron spectrum difference, were obtained from the k factors measured with the cold and thermal guided neutron beams of JRR-3M by statistical calculation. The prompt -ray emission probabilities were derived from the recommended k-factors using atomic weight, isotopic abundance and thermal neutron cross-section of other nuclear constants consisting the k factors, for which one can obtain accurate data. The derived -ray emission probabilities for the light elements (H to Ca) well agreed within 10% with those of the ENSDF, which reflect recent data, which the agreements for heavy elements (Ti to Pb) were 40% with those of the ENSDF, which are still composed of old data.

The present paper discusses a strategy for the development of a new radioactive decay database, which will succeed ICRP Publ.38 used for dosimetry calculations. The development of the database requires 1) Consistency checking of the ENSDF used for compilation of the decay data, 2) Improvement of the computer code EDISTR for processing the ENSDF, and 3) Comparison with other decay data prepared from the different computer codes and libraries for the verification of the compiled data. This paper identifies several technical issues that need to be addressed for the development of the new radioactive decay database.

Nuclear decay data, a set of data on half-life and energies and intensities of radiations emitted by nuclear transformation, are required in calculating external and internal doses by emissions from radionuclides. A nuclear decay database, which has been the most widely used for dose calculation in radiation protection, is Publication 38 (ICRP38) of the International Commission on Radiological Protection. The paper describes overview of ICRP38 and a future plan of its revision.

New nuclear decay data used for dose calculation have been compiled for 817 radionuclides that are listed in ICRP Publication 38 (Publ.38) and for 6 additional isomers. The decay data were prepared using decay data sets from the Evaluated Nuclear Structure Data File (ENSDF), the latest version in August 1997. Basic nuclear properties in the decay data sets that are important for calculating energies and intensities of emissions were updated by referring to NUBASE. In addition, possible revisions of partial and incomplete decay data sets were done for their format and syntax errors, level schemes, normalization records, and so on. After that, the decay data sets were processed by EDISTR in order to compute the energies and intensities of particles, particles, rays, internal conversion electrons, X rays, and Auger electrons. The compiled data were prepared in two different types of format: Publ.38 and NUCDECAY formats. The decay data will be widely used for dose calculations in radiation protection and will be beneficial to a future revision of ICRP Publ.38.
