kiirgusfüüsika
Kiirgusfüüsika, known in English as radiation physics, is the branch of physics that studies the generation, propagation, interaction, and effects of ionizing and non‑ionizing radiation. It encompasses both theoretical and experimental aspects, focusing on the properties of photons, electrons, neutrons, alpha and beta particles, and other charged or neutral particles that carry energy.
The field emerged in the early 20th century with discoveries such as X‑rays by Wilhelm Roentgen, radioactivity
Applications of kiirgusfüüsika are widespread. In medicine, it informs diagnostic imaging, radiotherapy, and radiation safety protocols.
Prominent contributors to kiirgusfüüsika include Enrico Fermi, who demonstrated nuclear fission, John von Neumann, who helped
