Radiation physics is the study of the behavior and properties of radiation, which includes particles and electromagnetic waves. This field examines how radiation interacts with matter, including its absorption, scattering, and transmission. Understanding these interactions is crucial for applications in medicine, industry, and environmental science. Key concepts in radiation physics include ionizing radiation, which can remove tightly bound electrons from atoms, and non-ionizing radiation, which does not have enough energy to cause ionization. The principles of radiation physics are essential for developing technologies such as X-rays, nuclear power, and radiation therapy for cancer treatment.
