2. having qualities or characteristics that broadcast well; suitable for presentation on the radio.

radiogenic

/ ˌreɪdɪəʊˈdʒɛnɪk /

adjective

1. produced or caused by radioactive decay

   a radiogenic element

   radiogenic heat

radiogenic

1. Being a stable element that is product of radioactive decay. For example, carbon 12 is often radiogenic, having been produced by radioactive decay of carbon 14.

2. Relating to the relation between radiogenic and radioactive elements, especially as a means of determining the age of objects, as in radiometric dating.

Example Sentences

According to the study authors, "the cenotectic plays a central role in the 'endgame' of planetary oceans. As large water-rich planetary bodies cool over geologic timescales or with loss of internal heating such as tidal dissipation or radiogenic heating, their oceans will gradually freeze from top to bottom, until complete solidification is achieved. This effect is particularly interesting in the case of large icy moons like Ganymede, Callisto, and Titan, but also for cold ocean exoplanets like Trappist 1e-g and water-rich rogue exoplanets."
