Word origin
The word 'radiation' comes from the Latin word 'radiatio', which means 'a shining, beaming, radiance'. The modern usage of the term in the context of nuclear science and medicine emerged in the early 20th century with the discovery of X-rays and radioactivity. Radiation plays a crucial role in various fields, from medical treatments to energy production, but also poses risks if not properly managed.
