Presentation Transcript


IAEA EMRAS Biota working group Future (suggested) plans


Potential areas of interest

  • ICRP interaction

  • New scenarios

  • Methodology

  • Improving parameter values

  • Link to wider ‘EMRAS II’


ICRP

  • Committee 4 discussions

  • Comparison and doses to humans and biota planned in PROTECT (BWG participation)


New scenarios

  • Will consider in next 6 months

    • Focused on current issues (planned and existing exposures)

    • Likely to included less studied radionuclides

  • Two initial proposals

    • U mining (link with NORM group – available scenario?)

    • Radioactive waste disposal


Methodology

  • Interface environments (eg estuaries)

  • Different situations (eg paddy fields)

  • Variability

    • Parameter distributions in approaches and how they are used

  • Radioecological sensitivity – does this need to be considered for biota??


Improving parameter values

  • Transfer CR values

    • Sub task group within BWG

    • Core group plus invited extras with relevant data

    • Interaction with ICRP/IUR

  • Effects information (link with UNSCEAR activities)

    • Quality / Quantity of data

    • Use of ecological population modelling?

      • Possibly adapting current models to move from individuals to populations
