Morphology

radio + silence

The meaning 'a period with no communication' is directly and predictably built from 'radio' (a communication/transmission medium) + 'silence' (absence of sound), so a learner who knows both words can infer that radio transmissions or contact have stopped. This compositional logic is straightforward and commonly extended to non-technical contexts, making the expression transparent to a B1 learner.

Etymology

The phrase radio silence comes from early radio work, when operators were told to keep the radio quiet and keep complete silence on the air so enemies could not hear them. So that literal 'no sound on the radio' is why today it means a period of 'no communication'.
