Radiation is a term that is commonly used in science and technology. It is a phenomenon that occurs when energy is emitted in the form of waves or particles. Radiation can be found in many forms, including light, heat, and sound. In this article, we will explore the definition and meaning of radiation, its origins, and its associations.
Definitions
Radiation is defined as the emission of energy in the form of waves or particles. It can be classified into two types: ionizing and non-ionizing. Ionizing radiation has enough energy to remove electrons from atoms, while non-ionizing radiation does not.
Origin
The word radiation comes from the Latin word “radiare,” which means “to emit rays.” The term was first used in the 17th century to describe the emission of light and heat from a source.
Meaning in different dictionaries
According to the Oxford English Dictionary, radiation is “the emission or transmission of energy in the form of waves or particles through space or through a material medium.” Merriam-Webster defines it as “the process of radiating or the state of being radiated.”
Associations
Radiation is associated with many different phenomena, including nuclear energy, X-rays, and electromagnetic waves. It is also associated with cancer and other health risks, as exposure to ionizing radiation can damage cells and DNA.
Synonyms
Some synonyms for radiation include emission, transmission, and irradiation.
Antonyms
Antonyms for radiation include absorption and reflection.
