Note (General): Nuclear decay data used for dose calculations have been compiled for 214 radionuclides with half-lives of less than 10 minutes. The decay data were assembled from decay data sets of the Evaluated Nuclear Structure Data File (ENSDF), the latest version as of May, 2007. Basic nuclear properties in the ENSDF that are particularly important for calculating the energies and intensities of radiations were examined and updated by referring to NUBASE2003/AME2003, the database for nuclear and decay properties of nuclides. In addition, modification of the incomplete ENSDF was done to determine their format errors, level schemes, normalization records, and so on. The energies and intensities of emitted radiations by the nuclear decay and the subsequent atomic process were computed from the ENSDF using the computer code EDISTR04. The compiled data are presented to enhance the nuclear decay database DECDC2, which was previously developed by the authors. The data will be used for dose calculations in the safety analysis for induced radionuclides in accelerator facilities and in treatment planning for the medical use of short-lived nuclides.
半減期10分未満の放射性核種214核種について、線量計算用の新しい核崩壊データを編集した。崩壊データは、2007年5月時点で最新の評価済み核構造データファイルENSDF(Evaluated Nuclear Structure Data File)から編集した。放射線のエネルギー及び強度を計算するうえで特に重要となる基本的な核特性は、核・崩壊特性に関するデータベースNUBASE2003/AME2003を参照し、更新した。また、不完全なENSDFに対しては、フォーマットの誤り、レベルスキーム,規格化定数等の分析を行い、それらの修正を行った。このENSDFから、原子核の崩壊及びそれに続く原子過程において放出される放射線のエネルギー及び強度を、EDISTR04コードを用いて計算した。編集されたデータは、著者らが既に開発した核崩壊データベースDECDC2を補強するものである。このデータは、加速器施設の誘導放射性核種に対する安全評価,短半減期核種の医療利用時の治療計画等における線量計算に利用される。
