2019 Work Programme

Review and enhancement of the BIOMASS-6 Reference Biosphere Methodology

The International Atomic Energy Agency (IAEA) BIOMASS-6 report on reference biospheres for solid radioactive waste disposal was published in 2003 following an extensive international collaborative work program. The report sets out a structured approach for the assessment of impacts of radionuclide releases to the biosphere from radioactive waste disposal facilities.  It also includes examples of the application of the methodology, called Example Reference Biospheres (ERBs) and associated results expressed in terms of radiation dose rates to humans for unit release rates of some relevant radionuclides.


With the focus of such assessments being on long-term future biosphere conditions, the methodology was intended to support the development of biosphere models as a measuring instrument, providing assessment results for comparison with protection objectives rather than a prediction of future conditions and exposures.


Given the significant developments in a wide range of factors including technical developments in models for radionuclide migration and accumulation, climate change model treatments and site investigation, characterisation methods and their interpretation, it is considered timely for the reference biospheres methodology to be internationally reviewed and enhanced to take account of this new knowledge and experience.
