In this report, the Commission provides biokinetic and dosimetric models for 33 radiopharmaceuticals as well as recommendations related to breast-feeding for mothers, who have undergone a nuclear medicine investigation. The report is based on Addenda 3-9 to ICRP Publication 53. Addenda 3-7 have been available on the ICRP web site (www.icrp.org) as interim reports. The work has been carried out in a joint Task Group of ICRP Committees 2 and 3. This Publication provides biokinetic models, absorbed doses and effective doses for the following radiopharmaceuticals: 11C-acetate, 11C-amino acids, 11C-brain receptor substances, 11C-methionine, 18F-amino acids, 18F-FET, 18F-FDG, 111In-monoclonal antibodies/fragments, 123I-fatty acid (BMIPP, IPPA), 123I-monoclonal antibodies/fragments, 131I-monoclonal antibodies/fragments, and 201Tl-ion. The Publication also provides realistic maximum models for 11C and 18F-substances, for which no specific models are available.
