kiirgamist

Kiirgamist is an Estonian term that broadly refers to the act of radiation or emission of energy, particularly in the form of electromagnetic waves. It encompasses various phenomena across different scientific disciplines. In physics, kiirgamist is often used to describe the emission of photons, such as light from a source or gamma rays from radioactive decay. This emission can occur spontaneously or be induced.

The concept also extends to thermodynamics, where it relates to thermal radiation, the emission of electromagnetic energy from matter due to its temperature. All objects above absolute zero temperature emit thermal radiation, with the intensity and spectral distribution depending on the object's temperature and properties. In a more general sense, kiirgamist can be used to describe the outward flow or spreading of something, such as the emission of radio waves from an antenna or the dispersal of heat from a warm surface. The specific context usually clarifies the precise meaning and the nature of the emitted energy.
