radiation
The emission or transmission of energy in the form of waves or particles. This includes, for example, radioactive radiation, thermal radiation, or light.
Zu viel UV-Strahlung von der Sonne kann die Haut schädigen.
Too much UV radiation from the sun can damage the skin.
The noun 'die Strahlung' (radiation) is derived from the verb 'strahlen' (to radiate/shine). The ending '-ung' turns a verb into a feminine noun that describes the process or result of the action.
Die Sonne strahlt heute besonders stark.
The sun is shining especially strongly today.
'Strahlung' (radiation) is often combined with adjectives that describe the type of radiation. Common examples are 'radioaktive Strahlung' (radioactive radiation), 'UV-Strahlung' (UV radiation), or 'elektromagnetische Strahlung' (electromagnetic radiation).
Radioaktive Strahlung kann für Lebewesen sehr gefährlich sein.
Radioactive radiation can be very dangerous for living beings.
To express that someone is exposed to radiation, you use the dative construction 'der Strahlung ausgesetzt sein' (to be exposed to radiation). To protect yourself, you use the preposition 'vor' with the dative: 'sich vor der Strahlung schützen' (to protect oneself from the radiation).
Die Arbeiter waren einer hohen Strahlung ausgesetzt.
The workers were exposed to high levels of radiation.

“Strahlung” mainly refers to energy transmitted in the form of waves or particles. “Ausstrahlung” can mean the same emission of energy, but it focuses more strongly on the source and its emitting energy, especially in the case of heat or light. When measuring the energy, “Strahlung” is more appropriate; when focusing on the source, “Ausstrahlung” is more appropriate.
Die Wärmestrahlung der Lampe war auf dem Messgerät deutlich zu erkennen.
The lamp’s thermal radiation was clearly visible on the measuring device.
Die Ausstrahlung der Lampe erwärmte den kleinen Raum langsam.
The radiation emitted by the lamp slowly warmed the small room.
