This report is a revision of ICRP Publication No 13. The recommendations it contains apply to the protection of pupils/students from ionizing radiation. They apply mainly to the teaching of natural science at secondary level, but they may be adapted to some forms of tertiary education.

The central dose quantities used in radiological protection are absorbed dose, equivalent dose, and effective dose. The concept of effective dose was developed by the International Commission on Radiological Protection (ICRP) as a risk-adjusted dosimetric quantity for the management of protection against stochastic effects, principally cancer, enabling comparison of estimated doses with dose limits, dose constraints, and reference levels expre...

Following the issuance of new radiological protection recommendations in Publication 103 (ICRP, 2007), the Commission released, in Publication 110 (ICRP, 2009), the adult male and female voxel-type reference computational phantoms to be used for the calculation of the reference dose coefficients for both external and internal exposures. While providing more anatomically realistic representations of internal anatomy than the older stylised phan...

This publication presents radionuclide-specific organ and effective dose-rate coefficients for members of the public resulting from environmental external exposures to radionuclide emissions of both photons and electrons, calculated using computational phantoms representing the ICRP reference newborn, 1-year-old, 5-year-old, 10-year-old, 15-year-old, and adult males and females. Environmental radiation fields of monoenergetic photon and electr...

This report describes the development and intended use of a series of ten computational phantoms representing the reference male and female at newborn, 1-year-old, 5-year-old, 10-year-old, and 15-year-old as defined in Publication 89. These phantoms have been formally adopted by the ICRP for use within ICRP Committee 2 in the development of age-dependent dose coefficients following the 2007 Recommendations. They are presented in this report in...

The purpose of this Publication is to provide guidance on radiological protection in industries involving NORM. These industries may give rise to multiple hazards and the radiological hazard is not necessarily dominant. The industries are diverse and may involve exposure to people and the environment where protective actions need to be considered. In some cases, there is a potential for significant routine exposure to workers and members of th...

Radiopharmaceuticals are increasingly used for the treatment of various cancers with novel radionuclides, compounds, tracer molecules, and administration techniques. The goal of radiation therapy, including therapy with radiopharmaceuticals, is to optimise the relationship between tumour control probability and potential complications in normal organs and tissues. This report provides an overview of therapy procedures and a framework for calcu...

This publication is intended to review, update and extend the information on the metabolism of plutonium, neptunium and the trivalent actinides, previously reviewed in ICRP Publication 19, with special reference to the absorption from the gastro-intestinal tract, the retention times in liver and skeleton, the influence of bone remodelling on the microdistribution within the skeleton and the relation of actinide metabolism to that of other radi...

ICRP Publication 21 contained data for protection against ionizing radiation from external sources. The data were of two kinds, one on the relationships between various radiation quantities, the other on the shielding properties of various materials. Some revised shielding data are now in ICRP Publication 33, which deals with external sources used in medicine: the other kind of data is considered here, but is not intended to apply to the irrad...

This publication is concerned with exposures of patients resulting from the administration of radiopharmaceuticals for diagnostic, therapeutic and research purposes, including some recommendations on protection of the patient's family. The report advises on the factors that influence absorbed doses (and hence radiation risks) to patients from different types of nuclear medicine examinations and indicates ways by which these risks can be minimi...

In 1977, the International Commission on Radiological Protection issued ICRP Publication 27, "Problems Involved in Developing an Index of Harm". That report discussed the difficulties of making an appropriate comparison of radiation and other effects and suggested a quantitative index to take account of the length of life or full activity lost as a result of occupational causes. This new report substantially extends the scope of ICRP Publicati...
