Etymology: Radiobiology is a compound built from two parts with very different histories. The "radio-" element comes from Latin "radius", meaning a ray or spoke of a wheel, which later gave English the word for radiation. The "biology" half runs back through New Latin "biologia" to Ancient Greek "bios", life, combined with "logos", study or discourse, so the whole word reads roughly as "the study of life" with "radiation" added in front. The combination is a plain, modern formation rather than an old word. Its meaning follows directly from its parts: the first element specifies what kind of biology is studied, namely the effects of radiation on living things. Because the two halves were joined in English only after both were established, the term describes a field defined by its subject matter rather than by any older tradition.

Synonyms: radiation biology, bio-radiology, radiation science, biological radiation, nuclear biology
