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 CaF2:Mn were irradiated in radiation fields of 137Cs and 60Co. Analysis of the measured results shows that at doses below 0.1 Sv, readers' outputs do not differ >5% from each other. At doses >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.
比较了内部开发并在斯洛文尼亚国家公共卫生研究所（JSI）使用的TL剂量测定系统MR200 TL的读数响应与在辐射与核安全管理局（RBI）使用的托莱多TL系统的读数响应。在0.01 mSv至5 Sv的不同剂量下进行了十次测量。一组36个装有三个CaF2:Mn颗粒的剂量计在137Cs和60Co的辐射场中进行了辐照。对测量结果的分析表明，在剂量低于0.1 Sv时，读数器的输出彼此之间的差异不超过5%。在剂量大于1 Sv时，MR200读数器获得的结果必须用一个已知因子进行校正。最后，测试了MR200结果的再现性。
