This course examines the principles of radiation protection and the biological effects of ionizing radiation. Students will learn about the sources of radiation exposure, the mechanisms of radiation interaction with biological tissues, and the potential health risks associated with radiation exposure. The course covers radiation safety standards, regulatory guidelines, and best practices for minimizing radiation exposure to patients, personnel, and the public. Emphasis is placed on understanding the principles of radiation protection, including time, distance, and shielding, as well as the use of dosimetry and protective equipment. Through theoretical instruction and practical applications, students will develop the knowledge and skills necessary to ensure safe and effective radiographic practice.
