Purpose and description of the content of education:
The lecture covers the following topics: Effects of the interaction of photon radiation with matter, including the biological environment. Quantities describing the absorption of photon radiation passing through matter, including linear and mass attenuation coefficients, energy transfer, and energy absorption. Interaction of electrons generated by photon absorption or produced in a linear accelerator with the biological environment. Quantities and units of ionizing radiation. Tissue-equivalent phantom materials. Therapeutic devices and generation of X-ray, electron, and gamma radiation beams. Interaction of photon beams with the scattering medium, including the definition of the following quantities: backscatter coefficient, percentage depth dose, tissue-air ratio, tissue-phantom ratio, beam profile, radiation beam field, and quality of photon radiation. Measurement of the beam output of X-ray and electron beams produced by linear accelerators. Planning of dose distributions of X-ray and gamma radiation beams for radiotherapy. Different types of ionization chambers (Farmer, Markus), their calibration specifics, and the methodology for dose determination using them. In vivo dosimetry using semiconductor detectors. In laboratory classes, students: Perform dose measurements using a wide range of dosimetric equipment, such as an ionization chamber with an electrometer, a radiometer with a Geiger-Muller counter, laboratory activity counters, scintillation probes, and thermoluminescent detectors. Learn the analysis of obtained results and the identification of dose dependencies on various physical factors. Familiarize themselves with the limitations of individual types of dosimetry equipment and analyze the areas of their applicability in clinical and environmental dosimetry. Learn to perform measurements in clinical dosimetry and analyze the results in terms of beam quality, such as measurement of dose at the depth of maximum dose (output of the linear accelerator), measurement of the percentage depth dose, and measurement of the percentage dose at a specified depth. Become acquainted with methods for quality control of selected dosimetry equipment, including determination of the calibration coefficient of a radiometer with a Geiger-Muller counter as a function of photon energy, determination of the individual sensitivity coefficient of thermoluminescent detectors, and gain skills in analyzing the obtained results in terms of equipment performance correctness.
