What does radiated mean?
Radiated is the past tense and past participle of radiate, meaning to send out light, heat, energy, or other radiation. It can also describe the outward communication of an emotion or personal quality: a speaker may radiate confidence, a performer may radiate charisma, or a place may radiate warmth. The literal sense is common in scientific, technical, and everyday descriptions, while the figurative sense suggests that a feeling or impression is so noticeable that it seems to spread from its source. In formal writing, “emitted” is often more precise when referring to measurable energy or radiation; in descriptive writing, “radiated” can convey a vivid impression of warmth, brightness, or emotional power. The word is especially useful when the source of something is not directly visible but its presence is unmistakable.
To emit or send out rays of light, heat, energy, or radiation; to spread or display a feeling or quality outwardly.
"The metal surface radiated heat throughout the laboratory."
The figurative use commonly takes an emotion or personal quality as its subject, such as confidence, warmth, or charisma.
Having rays or a radiant appearance; displaying a quality, such as happiness, in a striking and readily apparent way.
"He entered with a radiated sense of purpose that inspired the team."
This adjectival use is less common than the verb form and often sounds literary or descriptive.
A confident smile is said to be radiant, but even a smile can be radiated: its warmth reaches everyone in the room.

Where does radiated come from?
The word comes from Latin radiare, meaning “to emit rays” or “shine,” from radius, meaning “ray” or “spoke.” English borrowed the related forms radius, radial, radiation, and radiant, all of which share this Latin root. The verb radiate developed in English with both its physical sense of sending out rays and its figurative sense of expressing or displaying a quality that spreads outward.
