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 Publication 53. Addenda 3-7 have been available on the ICRP website (www.icrp.org) as interim reports. The work has been carried out by a Joint Task Group of ICRP Committees 2 and 3. This publication provides biokinetic models, absorbed doses, and effective doses for the following radiopharmaceuticals: C-11-acetate; C-11-amino acids;...

These revised Recommendations for a System of Radiological Protection formally replace the Commission's previous, 1990, Recommendations, and update, consolidate, and develop the additional guidance on the control of exposure from radiation sources issued since 1990. Thus, the present Recommendations update the radiation and tissue weighting factors in the quantities equivalent and effective dose and update the radiation detriment, based on the latest available scientific information of the biology and physics of radiation exposure. They maintain the Commission's three fundamental principles...

This report explains the process of estimating annual dose and recognises that a number of different methods are available for this purpose. These methods range from deterministic calculations to more complex probabilistic techniques. In addition, a mixture of these techniques may be applied. In selecting characteristics of the representative person, three important concepts should be borne in mind: reasonableness, sustainability, and homogeneity. Each concept is explained and examples are provided to illustrate their roles. Doses to the public are prospective (may occur in the future) or...
