Description	This study was concentrated on the assessment of the basic physical properties of polymer gel dosimeter evaluated by NMR. BANG-2 type polymer gel was prepared. The dosimeters were irradiated by 60Co gamma photons and by 4 MV, 6 MV and 18 MV X ray photonsby doses in the range of 0-50 Gy. Multi-echo CPMG sequence was used for the evaluation of T2-relaxation times in irradiated gel dosimeters. The dependence of 1/T2 response of dosimeters was studied on following factors: absorbed dose, energy of applied radiation, temperature during NMR evaluation, time since irradiation to NMR evaluation and strength of the magnetic field. An exponential dependence of 1/T2 response on absorbed dose in the range of 0-50 Gy was observed, in the range 0-10 Gy the data could be fitted by linear function. There was described the dependence of 1/T2 response on: energy, strength of magnetic field and time from irradiation of the dosimeters to NMR evaluation. Increase of gel dosimeter 1/T2 response with the d. This study was concentrated on the assessment of the basic physical properties of polymer gel dosimeter evaluated by NMR.
