Nobody thought of radiation. It was discovered.

Because Prof.Kodjo thought so
A type of weak radiation thought to be present due to quantum effects near a black hole's event horizon is often called Hawking radiation, after the scientist who proposed it, Professor Stephen Hawking.
Not everything: electromagnetic radiation, beta radiation, gamma radiation, particle beams etc. are not formed from elements.
The devastation of the Atomic Bomb was known but never thought to be needed twice. There was little known knowledge of the effects of radiation.
The term used to describe this duality of electromagnetic radiation is "wave-particle duality." It is a fundamental concept in quantum mechanics, where light and other forms of electromagnetic radiation exhibit characteristics of both waves and particles.
Electromagnetic radiation is one way that energy can be transfered across a distance. EM radiation can be thought of as packets of wave, each called a photon. A photon has a certain amount of energy, which can be found using the formula "E = hf", where 'f' is the frequency of the light, and 'h' is plancks constant (h = 6.626×10−34 Js).
Yes, all electromagnetic radiation, including visible light, radio waves, and X-rays, can travel through empty space (a vacuum). In a vacuum, all forms of electromagnetic radiation travel at the speed of light, which is approximately 299,792 kilometers per second (186,282 miles per second).
Infrared radiation, infrared, heat radiation.
Henri Becquerel was the first to discover that a penetrating radiation came from uranium, even if the uranium had not been exposed to sunlight. He thus showed that radioactivity was a fundamental property of uranium. Prior to his discovery, it was thought that any such radiation coming from uranium was the result of its interaction with sunlight.
