Morphology
The meaning is compositionally built: 'ionizing' (causing ionization) modifies 'radiation', so it literally denotes radiation that creates ions. This is a regular adjective + noun scientific formation and follows predictable morphological patterns found across languages, so a learner who knows 'ionize' and 'radiation' can derive the MWE meaning.
Etymology
Ionizing radiation comes from the picture of powerful rays changing atoms: the radiation hits an atom and knocks out tiny parts called electrons, so the atom becomes an 'ion'. The word ionizing names that action, so the phrase means rays strong enough to change atoms and make them charged.
