Radiobiology,
The Radiobiology course provides a detailed study of how radiation interacts with biological systems, focusing on the effects of ionizing radiation at molecular, cellular, and tissue levels. Students explore DNA damage, repair mechanisms, mutagenesis, and cell death pathways caused by radiation. The course highlights dose–response relationships, radiosensitivity differences among tissues, and both deterministic and stochastic effects. Emphasis is placed on clinical applications, particularly in radiotherapy, where understanding radiobiology helps maximize tumor control while minimizing harm to healthy tissues. It also covers radiation in diagnostic imaging, nuclear medicine, and its occupational and environmental hazards. Topics such as radiation protection, acute radiation syndrome, and long-term effects like carcinogenesis are discussed in depth. Practical examples and case studies link theory with real-world applications in medicine and research. By the end, learners gain the knowledge needed to apply radiobiological principles in healthcare, ensure patient safety, and contribute to advances in radiation-based treatments. المعهد الفني الصحي
