Note
A plural that only some meanings of radiation take comfortably. Most of them work as mass nouns for the phenomenon, the process or the energy itself, and they pluralize only to separate distinct kinds or sources, as with the radiations a sample emits. The evolutionary meaning, a rapid diversification of an ancestral species into many new forms, is always countable, so several radiations are simply several such diversifications.
