Advice and recommendations on design and implementation of internal dose monitoring programmes in the workplace

Advice was developed on routine and special monitoring following exposure to a range of radionuclides that represent some of the most difficult problems in internal dose assessment and are of the most radiological interest, ie tritium, cobalt-60, radioiodine, caesium-137, uranium, plutonium and thorium.

A novel aspect of the project was the development of a methodology to assess total uncertainty in intakes and doses assessed from monitoring measurements. Advice was also developed on ways of exploiting available methods and techniques to reduce uncertainties in measurements made for internal dose assessment purposes.

Recommendations are provided on choice of monitoring method(s), (eg excretion monitoring vs in vivo monitoring), choice of measurement technique (eg alpha spectrometry vs mass spectrometry), monitoring intervals, measurement frequency, required measurement sensitivity and accuracy, measurement parameters needed to achieve this performance, the resulting uncertainty in assessed intakes and doses, and minimum detectable doses. The work carried out provides a generic approach to the design and implementation of internal dose monitoring programmes.

Current status: Most of the work has been published in the open literature in scientific reports and papers. The remainder will be published in the open literature during 2004.

Potential application: Improved arrangements for internal dose monitoring in the nuclear industry.

End users: Dosimetry Service managers and senior medical staff in the nuclear industry, and nuclear industry regulators.

Main innovative features/benefits: Improved reliability in assessed internal radiation doses for workers in the nuclear industry, and reduction in costs of monitoring.

Market sector: Nuclear industry organisations, either state-operated or commercial (power generation, fuel cycle, etc.); commercial organisations offering dosimetry services.
