The CONRAD Project is a Coordinated Network for Radiation Dosimetry funded by the European Commission 6th
Framework Programme. The activities developed within CONRAD Work Package 5 (‘Coordination of Research on Internal
Dosimetry’) have contributed to improve the harmonisation and reliability in the assessment of internal doses. The tasks
carried out included a study of uncertainties and the refinement of the IDEAS Guidelines associated with the evaluation of
doses after intakes of radionuclides. The implementation and quality assurance of new biokinetic models for dose assessment
and the first attempt to develop a generic dosimetric model for DTPA therapy are important WP5 achievements. Applications
of voxel phantoms and Monte Carlo simulations for the assessment of intakes from in vivo measurements were also considered.
A Nuclear Emergency Monitoring Network (EUREMON) has been established for the interpretation of monitoring
data after accidental or deliberate releases of radionuclides. Finally, WP5 group has worked on the update of the existing
IDEAS bibliographic, internal contamination and case evaluation databases. A summary of CONRAD WP5 objectives and
results is presented here.
