Morphology

radio + brightness

The meaning is directly compositional: combining 'radio' (radio waves/emissions) with 'brightness' (degree of luminance/intensity) yields the idea of the intensity or strength of radio emission. This is a straightforward, commonly used scientific extension of 'brightness' and is likely inferable by a B1 learner who knows both constituent words.

Etymology

Radio brightness comes from early images made by large radio dishes, where strong radio signals showed up as bright spots on a screen. So 'radio brightness' now means the 'strength' or 'intensity' of a radio signal as seen by the telescope.
