Popis: Purpose: To foster quality assurance of dosimetry among the institutes involved in joint studies on late effects of ionizing radiation. Materials and methods: The participants in the dosimetry intercomparison received for each facility two mouse phantoms loaded with LiF thermoluminescent dosemeters (TLD) and a control badge. The participants were requested to irradiate the test phantoms in the actual arrangement used for whole body irradiation of mice, such that the dose in the centre of the test phantoms was 2 Gy and the dose distribution was uniform. The readout of the TLD and the dose evaluation were made at the organizing institute. Results: Ten institutes operating 14 exposure facilities in four countries took part in the intercomparison. For one facility a dose deviation between 5 and 10% was found, whereas for two others the deviation exceeded 10%. The requirement for uniform dose distribution in a mouse phantom was not fulfilled by six exposure facilities. The causes for the dose discrep...
