Dictionary definition of radiation

The emission or transmission of energy in the form of waves or particles through space or a material medium.
"The radiation emitted by the sun provides warmth and light to Earth."

Detailed meaning of radiation

It encompasses a broad spectrum of electromagnetic waves, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Additionally, radiation can also involve the release of subatomic particles, such as alpha and beta particles, as well as neutrons. This phenomenon occurs naturally, like the Sun's energy reaching Earth, as well as artificially, through various man-made sources like nuclear reactors, X-ray machines, and radioactive materials. While radiation has numerous applications in medicine, communication, and energy production, it can also pose risks to living organisms, depending on the type, intensity, and duration of exposure. Therefore, understanding and managing radiation are crucial in ensuring safety and mitigating potential hazards.

Example sentences containing radiation

1. The doctor explained the potential side effects of radiation therapy to the patient.
2. The workers wore protective suits to shield themselves from harmful radiation.
3. The Geiger counter detected high levels of radiation in the contaminated area.
4. The nuclear power plant implemented strict safety measures to prevent radiation leaks.
5. The oncologist used radiation to target and destroy cancer cells.
6. The astronaut's space suit was designed to protect against solar radiation in outer space.

History and etymology of radiation

The noun 'radiation' has its etymological origins in the Latin word 'radiatio,' which is derived from the verb 'radiare,' meaning 'to emit rays' or 'to shine.' This Latin root 'radiare' is closely connected to 'radius,' signifying a 'ray' or 'beam,' and it encapsulates the idea of emitting or transmitting energy in the form of waves or particles. Etymologically, 'radiation' refers to the act of emitting or transmitting energy through space or a material medium, much like the rays of light or energy that radiate from a central source. This connection to the emission of rays underscores the historical foundation of the term and its association with the spreading of energy in various forms.
