Occupational Internal Dosimetry

Course duration:

4 days



Course Summary

Please contact us at AcademyRegistrar@nv5com with any questions. We are excited to announce a revised Internal Dosimetry course which covers concepts and the practical application of internal dose calculations for radiation workers. These 4 days will be filled with everything from how to build a program to assessing intakes and doses. Come prepared to exercise different ways to evaluate doses using new and familiar tools and techniques. New to internal dosimetry? This course will take you through the fundamentals while giving you the tools you need to build up your program. A seasoned expert? This course will give you opportunities to test yourself and your program.

All conceptual bases and application details for ICRP internal dosimetry models for radiation works are described, with some practical calculational examples employed.

The ICRP 26/30 calculational framework is described and explained in detail, with examples. A brief review of the ICRP 2 system, which was the basis of our radiation protection system for many years is provided, as well as descriptions of the ICRP 60+ and ICRP 103 calculations and models (which have superseded ICRP 26/30, but not completely been adopted into regulations) is provided.

The ICRP kinetic models for inhalation, ingestion and wound intake routes are described in detail. Systemic models describing the distribution and retention of radionuclides are covered, with several important examples emphasized. Models for other specific situations (e.g. bone/marrow) are also explained, as they relate to the internal dosimetry of different radionuclides.

The very important ancillary topics of air sampling in the workplace and worker bioassay are reviewed. Methods and technologies of in-vivo and in-vitro bioassay are given and calculational methods for interpretation of bioassay data are covered, with numerical examples.

NRC guidance and regulations for internal dose assessment are reviewed. Specific types of facilities (nuclear power plants, uranium facilities, research and medical facilities) are covered with experiences in each described. Dosimetry models for dose to the fetus are also covered, with a brief review of existing internal dosimetry computer codes.

Special topics such as treatment for internal contamination, medical internal dose calculations, and others may be discussed.
