radiogenic

3 9.1
Formed when radioactive elements break down and release energy
  • adjective
  • /ˌreɪdiəʊˈdʒɛnɪk/
  • Specialized
: radiogénico
  • The presence of radiogenic materials can impact local geology and help explain volcanic activity.

Examples

  • Earth's heat output from radiogenic elements is estimated at about 20 terawatts, roughly half of the heat currently leaving Earth's interior.

    Academic text (2005)
  • The radiogenic elements in the soil contribute significantly to the heat produced within the Earth's crust.

  • Scientists study radiogenic isotopes to understand the age of geological formations accurately.

radiogenic positive

Morphology

radiogenic = radio (semi-transparent) = radio + genic

The word is built from the scientific combining form radio- and the suffix -genic, but both elements are specialized enough that many learners will not parse the meaning immediately.

Etymology

Radiogenic comes from the parts radi- meaning 'ray' or 'radiation' and -genic meaning 'born' or 'produced', like in 'generate'. So, calling heat or gases radiogenic means they are 'produced by' the slow break down of radioactive material inside the Earth.
