Definition
辐射 (fú shè) specifically means 'to radiate' in the sense of emitting radiation, heat, or light as waves/particles — the technical term in physics and medicine. 放射 (fàng shè) is a close synonym, but 辐射 focuses on the radiation itself while 放射 can also refer to the act of emitting; 散发 (sàn fā) is broader, meaning 'to give off' a smell, heat, or light, not necessarily as radiation.
