Radiation Physics

📘 About Radiation Physics

Radiation Physics is a specialized branch of physics that deals with the study of ionizing and non-ionizing radiation, its interactions with matter, and its practical applications in medicine, industry, and research. It covers the fundamental principles of radioactive decay, radiation detection and measurement, and radiation protection.

This field is especially important in medical imaging, cancer treatment (radiotherapy), nuclear medicine, and ensuring safety standards in environments exposed to radiation. Radiation physics forms the scientific basis for many diagnostic and therapeutic technologies used in healthcare today.
