  Organized by Working Group 6 "Computational Dosimetry" of the European
Radiation Dosimetry Group (EURADOS), a group of intercomparison exercises was
conducted in which participants were asked to solve predefined problems in
computational dosimetry. The results of these comparisons were published in a
series of articles in this virtual special issue of Radiation Measurements.
This paper reviews the experience gained from the various exercises and
highlights the resulting conclusions for future exercises, as well as regarding
the state of the art and the need for development in terms of quality assurance
for computational dosimetry techniques.
