ICRP Publication 137: Occupational Intakes of Radionuclides: Part 3.

Area of Science:

• Radiation Protection
• Internal Dosimetry
• Occupational Health

Background:

• The 2007 International Commission on Radiological Protection (ICRP) recommendations necessitate updates to effective dose calculations.
• Previous dose coefficients (ICRP Publication 30 series, Publication 68) and radionuclide data (Publications 54, 78) require revision.
• New biokinetic models and dosimetric data are available for improved occupational internal dose assessment.

Purpose of the Study:

• To revise and update dose coefficients for internal exposure following ICRP 2007 recommendations.
• To provide new biokinetic models, dose coefficients, and monitoring methods for radionuclides.
• To introduce the Occupational Intakes of Radionuclides (OIR) series, replacing previous ICRP publications.

Main Methods:

• Development of new biokinetic models and dose coefficients by ICRP Committee 2 Task Groups.
• Compilation of radionuclide-specific information, including chemical forms, isotopes, and physical properties.
• Generation of dosimetric data for inhalation and ingestion, including committed effective dose per intake and content.

Main Results:

• The Occupational Intakes of Radionuclides (OIR) series is established to replace ICRP Publications 30, 54, 68, and 78.
• OIR Part 1 and Part 2 provide comprehensive guidance on internal exposure assessment and biokinetic/dosimetric models.
• This publication (OIR Part 3) presents updated data for ruthenium, antimony, tellurium, iodine, caesium, barium, iridium, lead, bismuth, polonium, radon, radium, thorium, and uranium.

Conclusions:

• The OIR series provides essential updated data for occupational internal dosimetry.
• New biokinetic and dosimetric models enhance the accuracy of dose assessments.
• The comprehensive data facilitate improved monitoring programs and retrospective dose evaluations.
