Precision nuclear data for extended radionuclide offer

Nuclear decay data are fundamental constants of a radionuclide’s decay process and are unique to that radionuclide. Nuclear decay data are of importance to a wide range of activities in nuclear medicine, from the production of radionuclides to their use in nuclear medicine clinics. Thus, accurate and precise nuclear decay data are vital to ensure confidence in the activities undertaken across the end-to-end process of radiopharmaceutical use. During the progress of PRISMAP the number of radionuclides has increased from an original offering of 18 radionuclides to an extensive portfolio of 28 radionuclides. In a previous report the status of the nuclear decay data of these original 18 radionuclides was reviewed and recommendations given where future measurement campaigns were needed to improve this data. This same undertaking has been performed for the extended offering of radionuclides, adding reviews of the radionuclides of Sc-43, Mn-52, Pd-103, Rh-103m, Ba-138, Cs-128, Sm-153, Au-199, Pb-203, Ra-223 (and its six-decay progeny), Ra-224 (and its six-decay progeny) and Th-227. A summary of the current state of nuclear decay data of these radionuclides have been covered in this report using the latest evaluations published by the Nuclear Data Sheets or the Decay Data Evaluation Project. Where recent studies have been published since the last evaluation a comparison to these new values have been included. Based on these reviews, recommendations have been proposed throughout the report for new nuclear decay data studies, where the current literature is lacking or there is room for improvement.
