English Abstract During the period March through October 1989, the Sixth
EULEP X-ray Dosimetry Intercomparison on whole-body irradiation on mice was
performed. The intercomparison consisted of two irradiation series; the
initial study comprised 15 participating institutes, the second series were
performed for 7 institutes which showed appreciable deviation from the
reference value. The participants performed irradiations of mouse phantoms
containing TL dosemeters. The read-out and evaluation of the TL dosemeters
were perfomed at RIVM. The accuracy and precision of the dosimetry can be
considered satisfactory for most of the participants. Deviations observed
at several institutes indicate the need for site-visits to trace probable
systematic errors.
