ICRP Publication 151 - Occupational Intakes of Radionuclides: Part 5

ID 21312 | 06.02.2024

This publication is the fifth and the last in a series dedicated to occupational intakes of radionuclides (OIR), which replaces the Publication 30 series (ICRP, 1979a,b, 1980, 1981, 1988) and Publications 54, 68, and 78 (ICRP, 1989, 1994a, 1997). The first publication of this new series (OIR Part 1) describes the assessment of internal occupational exposure to radionuclides, biokinetic and dosimetric models, methods of individual and workplace monitoring, and general aspects of retrospective dose assessment.

The following publications of the series (OIR Parts 2–5) provide data on individual elements and their radioisotopes, including information on chemical forms encountered in the workplace; a list of principal radioisotopes and their physical half-lives and decay modes; the parameter values of the reference biokinetic models; and data on monitoring techniques for the radioisotopes most commonly encountered in workplaces. For most of the elements, reviews of data on inhalation, ingestion, and systemic biokinetics are also provided.

Dosimetric data provided in the printed publications of the series include tables of committed effective dose per intake (Sv per Bq intake) for inhalation and ingestion, tables of committed effective dose per content (Sv per Bq measurement) for inhalation, and graphs of retention and excretion data per Bq intake for inhalation. These data are provided for all absorption types and for the most common isotope(s) of each element.

The online electronic files that accompany the OIR series of publications contain a comprehensive set of committed effective and equivalent dose coefficients, committed effective dose per content functions, and reference bioassay functions. Data are provided for inhalation, ingestion, and direct input to blood. This publication provides the above data for the following elements: beryllium, fluorine, sodium, magnesium, aluminium, silicon, chlorine, potassium, scandium, titanium, vanadium, chromium, manganese, nickel, copper, gallium, germanium, arsenic, selenium, bromine, rubidium, rhodium, palladium, silver, cadmium, indium, tin, hafnium, tantalum, tungsten, rhenium, osmium, platinum, gold, mercury, thallium, astatine, and francium. Additional dosimetric data for exposure from submersion in a cloud of gas are given in Annex A for the noble gases neon, argon, krypton, and xenon.
