Morphology
radio + radiation
The meaning 'electromagnetic waves in the radio-frequency range' is directly derivable from combining 'radio' (relating to radio waves or radio transmission) with 'radiation' (energy emitted as waves). This modifier–noun compositional pattern is transparent and cross-linguistically common, so a B1 learner who knows both constituents would readily infer the intended meaning.
Etymology
Radio radiation comes from the image of invisible rays spreading out from a source. The word radio suggested 'rays' or 'beams' and radiation means 'sending out', so the phrase helps you picture energy spreading like light and means 'electromagnetic waves for radio communication'.
