Säteilykenttien, often translated as radiation fields, refers to the spatial distribution of electromagnetic radiation or energetic particles. These fields are characterized by their intensity, frequency or energy, and directionality. In physics, the concept of a radiation field is fundamental to understanding phenomena ranging from the behavior of light to the interaction of cosmic rays with matter.

Electromagnetic radiation fields, such as visible light, radio waves, or X-rays, are described by oscillating electric and magnetic fields propagating through space. The properties of these fields determine the type of radiation and its interactions with objects, influencing how we perceive the world and enabling technologies like communication and medical imaging.

Fields of energetic particles, like those from radioactive decay or solar flares, involve streams of charged or neutral particles possessing significant kinetic energy. Their behavior is governed by electromagnetic forces and their own momentum. Understanding these particle radiation fields is crucial in fields such as nuclear physics, astrophysics, and radiation protection. The intensity and composition of these fields can have profound effects on biological tissues and electronic systems, necessitating careful measurement and control in various scientific and industrial applications.
