Etymology
Meaning and Origin
The word "radiation" originally referred to the emission or transmission of energy in the form of waves or particles. It is derived from the Latin verb "radiare," meaning "to radiate, emit rays."
This verb is in turn derived from the Indo-European root h₁reh₁-/, which means "to shine." The same root also gives rise to other words related to light and brightness, such as "ray," "radius," and "rainbow."
In physics, radiation refers to the emission or propagation of energy in the form of electromagnetic waves or particles, including alpha particles, beta particles, and gamma rays.
The term is often used in the context of nuclear reactions and the release of energy from radioactive materials.
