Sub-Group on Retrospective Assessments
Terms of reference
The aim of the sub-group is to assist in the development of a
suitable methodology for use by the Environment Agencies in fulfilling
their responsibility to assess and report total doses.
In particular the sub-group will:
- Comment on the EA report on 'The development of a methodology
to assess population doses from multiple sources and exposure
pathways of radioactivity'.
- Suggest changes and improvements that might be made to the
methodology.
- Review any trials of the methodology.
- Consider related issues such as the use of measurement data
in retrospective assessments including values less than reporting
limits.
- Consider methods for defining the critical group (e.g. the
Hunt and Shepard approach or using the 97.5th percentile).
- Discuss and propose plans for regular reporting of total retrospective
doses to members of the public.
- Provide advice on the implementation of the total assessment
methodology to encompass both nuclear and non-nuclear sites.
