IAEA Coordinated Research Project: Updated decay data library for actinides

Alpha-particle spectrometry for the determination of alpha emitting isotopes in nuclear, environmental and biological samples: past, present and future

“…The need to determine accurate decay data of various actinide radionuclides was identied by IAEA. 125,126 The scientists from CIEMAT, Madrid, Spain and IRMM (formerly CBNM), Geel, Belgium have been continuing an excellent collaboration and cooperation for more than two decades, and have produced the best data on the a-particle emission probabilities of several important radio-nuclides. [127][128][129][130][131][132][133][134][135][136][137][138][139] For the accurate determination of a-particle emission probabilities of different a-emitters, sources prepared by vacuum sublimation from a tungsten lament, of isotopically pure nuclides (99.9% or better) and high radiochemical purity, on quartz , and with a 150 mm 2 PIPS detector (to optimize the resolution and counting statistics) for a-emission probabilities.…”

Experimental studies to improve specific actinide decay data

“…This project is coordinated by M.A. Kellett of the IAEA Nuclear Data Section, and two Research Coordination Meetings have already taken place at IAEA Headquarters in Vienna [6,7]. After the completion of the project, the resulting evaluated data files will be made available in both ENSDF and ENDF-6 formats so that they can be promptly incorporated into the specialized data libraries used by the applied nuclear community.…”
