In March 1987 the International Commission on Radiological Protection established a Task Group which was requested "to evaluate dose per unit intake for members of the public." In Section I, this report incorporates age-dependent physical models and appropriate biokinetic information. Section II reports on doses per unit intake of isotopes of hydrogen, carbon, strontium, zirconium, niobium, ruthenium, iodine, caesium, cerium, plutonium, americium and neptunium. Detailed appendices give extensive information on bone models for actinides, and inhalation dose coefficients.

Ingestion Dose Coefficients The present report on age dependent dose coefficients to members of the public follows ICRP Publications 56 and 67. The following elements are covered: iron, selenium, antimony, thorium and uranium. This report gives parameters for the tissue distribution and retention of these elements together with data on urinary and faecal excretion. Dose coefficients have been calculated for radioisotopes of these elements which are expected to be released into the environment as a result of human activities and are considered to be of significance for environmental radiation...

A Task Group of the ICRP Committee 1 (Radiation Effects) has reviewed relevant data with the objective of advising the Main Commission of the ICRP on the possible implications for radiological protection of emerging views on genetic susceptibility to cancer. Chapters consider DNA damage, the mechanisms and genetics of solid tumours, lympho-haemopoietic tumours, commentary data and the development of computational modelling procedures that aim to describe the impact of genetic factors on radiation-tumorigenesis in human populations. The report is preliminary and serves principally to provide a...

One of a series of reports recommending Annual Limits for Intakes (ALI's) of radionuclides by workers. The data given in this report is intended to be used in conjunction with text and dosimetric models described in Part 1 of the ICRP Publication 30.

One of a series of reports recommending Annual Limits for Intakes (ALI's) of radionuclides by workers. Includes ICRP Progress Report on the Preparation of the New Recommendations.

This report is intended to guide radiologists and others concerned with diagnostic radiology with regard to the factors that influence radiation doses, and hence radiation risks, from different types of X-ray examination. It supersedes Publication Number 16 on the same subject.

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 minimized without detriment to intended medical benefits. This report supersedes ICRP publication 17 and, together with ICRP publications 34 and 44, completes...

The Commission's 1990 recommendations on radiation protection standards in ICRP Publication 60 were developed to take into account new biological information related to the detriment associated with radiation exposures and supersede the earlier recommendations in ICRP Publication 26. In order to permit immediate application of these new recommendations, revised values of the Annual Limits on Intake (ALIs) based on the methodology and biokinetic information and incorporating the new dose limits and tissue weighting factors, wT were issued as ICRP Publication 61. Since issuing ICRP Publication...

High-dose-rate (HDR) brachytherapy is a rapidly growing technique that has been replacing low-dose-rate (LDR) procedures over the last few years in both industrialised and developing countries. It is estimated that about 500,000 procedures (administrations of treatment) are performed by HDR units annually. LDR equipment has been discontinued by many manufacturers over the last few years, leaving HDR brachytherapy as the major alternative.

HDR brachytherapy techniques deliver a very high dose, of the order of 1.6-5.0 Gy/min, so mistakes can lead to under- or over dosage with the...

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 irradiation of patients. The main reason for this revision is to adapt the data and the underlying approach to the Recommendations of the International...
