  This paper is the editorial of a special issue of Radiation Measurements on
EURADOS intercomparisons in computational dosimetry. The articles in this
special issue cover complex problems in terms of geometry, particle types,
energy ranges, coupled calculations and also scale, with the possibility of
performing Monte Carlo calculations on micro and nano dosimetric scales now
feasible. A summary of the exercises is provided in the first article of the
Special Issue, which presents the findings and common conclusions from the ten
articles reporting the results of the different exercises. One of these issues
was the correct assessment of bone marrow dose, which prompted the inclusion of
an article in this special issue explaining the ICRP-recommended method for
bone marrow dosimetry.
