As a primary laboratory in the field of ionizing radiation metrology, the LNE-CEA/LNHB is involved in measurement, evaluation and dissemination of radioactive decay data. Data measurements obtained by various laboratories are evaluated by an international group of experts (Decay Data Evaluation Project) in order to establish a set of recommended decay scheme data. Those data are subsequently distributed to users through various tools developed in our laboratory and well suited to each application domain. They are presented in an exhaustive and documented way through the publication of a multi-volume printed monograph (Monographie BIPM-5), for which a new issue has been released by the end of 2006. This monograph is recommended as a reference database by the CCRI (Comité Consultatif des Rayonnements Ionisants) of the BIPM. Those data can also be accessed via a specific software Nucléide whose database contains more than 300 nuclides of particular interest. In the field of alpha and gamma spectrometry, a web application has been specially developed in order to present the major emissions of a given nuclide. Moreover, it allows to find nuclides corresponding to search criteria on their emission energies or intensities. Finally a booklet version of this database will soon be published. It will present in a concise way the main alpha, X, gamma and electron emissions and their half-life, for some 250 nuclides. This paper intends to describe some features of these tools and publications.
