Course Description
RAD 110 | Radiation Physics & Safety in Medical Imaging Total: 16 Hours | E-Lecture: 8 Hours | E-Lab: 8 Hours | On Site Lab: 0 Hours This course offers a strong foundation in radiation physics, focusing on the role of radiation in medical imaging and the advantages of ultrasound over ionizing modalities. Students will study electromagnetic and mechanical waves, comparing ionizing radiation (X-rays, gamma rays) with non-ionizing methods (ultrasound, MRI). The physics of radiation production, interaction with matter, and biological effects are covered to highlight why ultrasound is a safer diagnostic tool. Hands-on activities include using Geiger counters, EMF detectors, and compasses to measure radiation in various materials like ceramic, granite, and marble. Students will explore natural radiation distribution, environmental contamination, and health-conscious practices, including strategies for reducing exposure through water, air, and food filtration. The course emphasizes radiation safety, the biological impact of EMFs, and oxidative stress. Through case studies, students will gain practical skills to minimize risks, communicate effectively with patients and colleagues, and advocate for safer imaging practices. Future sonographers will be empowered to recognize the unique value of ultrasound in diagnostic healthcare.
