The objective of the working group is to bring together all recent, available, preferably published, experimental data and results of calculations, with detailed descriptions of methods of measurement and calculation, in particular from European research groups

The purpose is to provide a data set for all Member States for the assessment of individual doses and/or to assess the validity of different approaches, and to provide an input to technical recommendations by the Article 31 group of experts and the EC.

The quantity of interest is effective dose, E(ISO), but the comparison of measurement results obtained by different methods or groups, and comparison of measurement results and the results of calculations should be done in terms of the operational quantity ambient dose equivalent, H*(10).

The report giving the results of the investigations would be published by the EC DG ENV.
