Radiativ

Radiativ is an adjective used in technical and scientific contexts to describe phenomena associated with or caused by radiation. The term is found in some languages, where it functions similarly to the English radiative to characterize processes involving emission, absorption, or transfer of electromagnetic radiation or particle radiation.

In physics, radiativ describes radiative transfer in atmospheres or stellar interiors, radiative cooling of surfaces, or radiative heating from radiation sources. In engineering, radiativ components include radiative heat exchange surfaces and radiative shields. In astronomy, radiativ transfer equations describe how light propagates through matter.

Distinctions. Radiative processes are contrasted with non-radiative mechanisms such as conduction or convection. Radiativ effects are often described by quantities like radiative flux, emissivity, absorptivity, and the radiative transfer equation.

Etymology and variants. The form radiativ appears as an adjective in several European languages as a cognate of the English radiative. English uses radiative more commonly; radiativ may appear in translations, glossaries, or technical literature from languages that render the final -e differently.
