Monographie BIPM-5: Table of radionuclides

Preface:

    This monograph is one of several published in a series by the Bureau International des Poids et Mesures (BIPM) on behalf of the Consultative Committee for Ionizing Radiation (Comité Consultatif des Rayonnements Ionisants, (CCRI)1). The aim of this series of publications is to review topics that are of importance for the measurement of ionizing radiation and especially of radioactivity, in particular those techniques normally used by participants in international comparisons. It is expected that these publications will prove to be useful reference volumes both for those who are already engaged in this field and for those who are approaching such measurements for the first time.

    The purpose of this monograph, number 5 in the series, is to present the recommended values of nuclear and decay data for a wide range of radionuclides. Activity measurements for more than sixty-three of these radionuclides have already been the subject of comparisons under the auspices of Section II (dedicated to the Measurement of radionuclides) of the CCRI. The material for this monograph is now covered in seven volumes. The first two volumes contain the primary recommended data relating to half-lives, decay modes, x-rays, gamma-rays, electron emissions; alpha- and beta-particle transitions and emissions, and their uncertainties for a set of sixty-eight radionuclides, Volume 1 for those radionuclides with mass number up to and including 150 and Volume 2 for those radionuclides with mass number over 150. Volume 3 contains the equivalent data for twenty-six additional radionuclides as listed and re-evaluations for 125Sb and 153Sm; Volume 4 contains the data for a further thirty-one radionuclides with a re-evaluation for 226Ra and Volume 5 includes seventeen new radionuclide evaluations and eight re-evaluations of previous data as identified in the contents page. Volume 6 contains twenty-one new radionuclide evaluations and four reevaluations for 64Cu, 236Np, 237Np and 239U. Volume 7 contains twenty-four new radionuclide evaluations and five re-evaluations, for 67Ga, 208Tl, 228Th, 242Cm and 244Cm. The present Volume 8 contains twenty-three new radionuclide avaluations and nine re-evaluations for 88Y, 93mNb, 109Cd, 131I, 131mXe, 133Ba, 140Ba, 140La and 198Au .The data have been collated and evaluated by an international working group (Decay Data Evaluation Project) led by the Laboratoire national de métrologie et d'essais - Laboratoire national Henri Becquerel (LNE-LNHB).

    The evaluators have agreed on the methodologies to be used and their comments for each radionuclide in addition to the data tables in the present monograph can now both be found on the BIPM website.

    The work involved in evaluating nuclear data is ongoing and the recommended values are kept up to date on the LNE-LNHB website at http://www.nucleide.org/DDEP_WG/DDEPdata.htm.

    The BIPM and the DDEP are most grateful to the International Atomic Energy Agency (IAEA) for their assistance and financial support to some evaluators in the production of data for Volumes 1 to 3 through their Coordinated Research Project "Update of X Ray and Gamma Ray Decay Data Standards for Detector Calibration and Other Applications" and for Volumes 4 to 7 through their Coordinated Research Project "Updated Decay Data Library for Actinides" and for Volume 8 through their Coordinated Research Projects "Testing and Improving the International Reactor Dosimetry and Fusion File (IRDFF)" and "Nuclear Data for Charged-particle Monitor Reactions and Medical isotope Production". The BIPM and the DDEP are indebted also to some other evaluators who participate in the United States Nuclear Data Program (USNDP) for their support to these publications.

    The publication of further volumes of Monographie 5 is envisaged when necessary to add new radionuclide data or re-evaluations in this more permanent format that can be referenced easily.

    Although other data sets may still be used when evaluating radionuclide activity, the CCRI encourages the use of this common, recommended data set that should help to reduce the uncertainties in activity evaluations and lead to more coherent results for comparisons (2009, CCRI Report of 21st meeting, section 17.2).
