This paper reports on the results of a common NIRAS/ONDRAF (Belgium) - CEA/IPSN (France) project, within the framework of a study-contract with the Commission of the European Communities (No. CT-FI2W/0060). It describes the different landfill disposal techniques in France and in Belgium together with the exposure pathways and the parameters needed as input to the computer codes CERISE and GEOLE, which have been developed to assess the radiological impact of landfill disposal of very low level radioactive waste. The results of the individual dose calculations for workers and the public and the derived activity concentration and contamination levels for acceptance to landfill sites will be presented. Finally, a comparison will be made between the sets of derived levels as they are related to the different landfill disposal practices in the two countries. (author). 3 refs, 6 figs, 2 tabs.
