Sažetak
The results of TLD-700 irradiations with 3 MeV protons using Tandem Van de Graaff accelerator are shown. In order to estimate the contribution of X-rays, CaF_2:Mn TL detectors were also irradiated at the same condition as TLD-700. Due to the presence of low energy X-rays, the peak area method of high-temperature peak 7 of TLD-700 was found to be more suitable for proton dose determination. TL efficiency for protons using this peak relatively to ^137Cs gamma rays was calculated. The relative responses (peak 7)_p/(peak 5)_gamma and (peak 7)_p/(peak 7)_gamma of 0.16 and 9.6, respectively were obtained. Taking into account the self-absorption of the TL photons in the dosimeter the relative efficiency for peak 7, ni_p, gamma, = 8.0 was found.
