Surface Forms

electron radiation singular

electron radiations plural

Morphology

electron + radiation

The phrase denotes radiation made up of electrons — combining 'electron' (a negatively charged particle) with 'radiation' (energy emitted as particles or waves) directly yields the intended meaning. Although somewhat technical, this noun–noun composition is compositional and cross-linguistically regular, so a B1 learner who knows both constituents can reasonably infer the meaning.

Etymology

Electron radiation comes from the image of an unstable atom 'giving off' tiny charged particles called electrons that fly away as radiation. That's why the term means 'emission of electrons' during 'radioactive decay'.
