Morphology

alpha + radiation

The noun is compositionally built from 'alpha' modifying 'radiation' (radiation = emitted energy), so if a learner knows 'alpha' refers to alpha particles they can derive the meaning as radiation made of alpha particles. However, 'alpha' is a technical/scientific term (often only known as a Greek letter by B1 learners), so the specific particle sense is not fully predictable without domain knowledge, making the expression only partially transparent.

Etymology

Alpha radiation comes from early scientists who called the first kind of rays 'alpha' and used radiation to mean 'rays sent out'. That's why the name refers to the strong rays that do not travel far and can be stopped by simple barriers like paper.
