Abstract
The 1st part of this thesis discusses the EPR spectroscopic parameters for the radiation-induced radicals in SrSO4 (SS) rod dosimeters in the radiotherapy dose range (0.5 to 25 Gy) to choose the suitable parameters to obtain a good signal-to-noise ratio. These parameters are microwave power, modulation amplitude, sweep width, receiver gain, time constant, conversion time, and the number of scans.
In the 2nd part, the radiation-induced radicals in the crystals of SS rod dosimeters and dosimetric characteristics were studied using an EPR spectrometer in the dose range of (0.5 to 25 Gy) for radiotherapy of 60Co γ-rays and high megavoltage X-ray with 6 and 15 MV. Additionally, the obtained behavior of this dosimeter was compared to the standard alanine dosimeter at these beam qualities.
In the 3rd part, the reference dosimetry protocol based on using a PTW PinPoint ionization chamber was compared with alanine dosimetry at the European Synchrotron Radiation Facility (ESRF) ID17 Biomedical beamline, an orthovoltage X-ray source with an average dose rate of 11.6 kGy/s. Reference dose measurements of the alanine pellets at the ESRF were compared to 60Co gamma rays as a reference beam quality.
In the 4th part, two dosimeters of strontium sulfate (SS) and strontium carbonate (SC) rods were prepared, studied at ESRF with an orthovoltage X-ray source (30-600 kV with an effective energy of 99 kV), and compared with the response at the ESRF with at a 60Co beam. The response of these dosimeters was investigated in the dose range of 50 to 5000 Gy compared to 60Co γ-ray irradiation.
