Özet

In recent years, novel materials with protective qualities against ionizing radiation have been discovered. Important concepts include the continued use of X-rays for diagnosis and treatment, particularly in the radiological energy range, as well as the calculation of the radiation attenuation properties of such materials, the build-up factor, and the attenuation coefficients. Radiation shielding is characterized by parameters such as linear attenuation coefficient (LAC, cm-1),.equivalent atomic number (Zeq), exposure buildup factors (EBF) and exposure absorption buildup factors (EABF). Radiation is often employed in the diagnosis and treatment of cancer and accurately calculating the absorbed dosage during radiation treatment, which is one of the most popular cancer treatments. It relies on accurate modeling of the radiation beams administered to the patient and their interaction with the environment in which they are absorbed. In this research, the shielding characteristics of water, fat, and bone related to human tissue are investigated. Using Phy-X/PSD software, the equivalent atomic number (Zeq), exposure buildup factor (EBF), and energy absorption buildup factor (EABF) were determined.
