Sažetak
Detailed measurements of sensitivity, linearity, supraliearity and fading of the TLD-100, TLD-700, CaF2:Mn and Al2O3:Mg, Y detectors with various encapsulations were carried out to asses the suitability of these detectors for measuring total gamma dose in amixed n+gamma irradiation field during the International Intercomparison of the Criticality Dosimetry Systems organized by the Commission of European Communities at SILENE Reactor in Valduc, 1993. After mixed field irradiation, some detectors were read at Valduc, others at the Ruđer Bošković Institute (RBI). The readings have shown the agreement between the Valduc and RBI gamma field calibrations. After readout the recalibration of the response to gamma rays and accurate determination of fading kinetics was performed. No change of sensitivity after neutron irradiation could be observed with TLD-700 and CaF2:Mn detectors. The reproducibility of Al2O3:Mg, Y detectors deteriorated somewhat, with no systematic change of sensitivity. The sensitivity of TLD-100 detectors changed after neturon irradiation.
