Intercomparison of dosimetry systems based on CaF_2:Mn TL detectors

The responses of readings by the TL dosimetry system MR200 TL developed in-house and used at JSI and the TOLEDO TL system used at RBI are compared. Ten measurements at different doses ranging from 0.01 mSv to 5 Sv were carried out. A set of 36 dosemeters with three pellets of CaF_2:Mn were irradiated in radiation fields of 137^Cs and 60^Co. Analysis of the measured results shows that at doses below 0.1 Sv, readers' outputs do not differ more than 5%from each other. At doses more than 1 Sv, the results obtained by the MR200 reader must be corrected with a known factor. Finally, the reproducibility of the results from the MR200 was tested.
