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.
wave
'Welle' and 'Strahlung' can both occur in physics, especially when talking about light, heat, or radio signals. A 'Welle' describes the form of propagation: an oscillation moves through space. 'Strahlung', on the other hand, means the transmission of energy, for example through light, heat, or radioactive particles. Learners may confuse the words because radiation often occurs in the form of waves. In practical terms: 'Welle' fits when you are describing the movement or form; 'Strahlung' fits when the topic is energy and its effect.
Die Ärztin erklärt, warum zu viel UV-Strahlung der Haut schaden kann.
The doctor explains why too much UV radiation can harm the skin.
Eine Schallwelle breitet sich durch die Luft aus.
A sound wave spreads through the air.
