Etymology: "Radiographs" is the plural of "radiograph," a compound built from the Latin "radius" (ray) and the Greek-derived suffix "-graph" (writing or drawing). The literal sense is "ray-writing," and the word is a modern formation rather than an ancient one: "radiograph" appears in the 1890s, shortly after Wilhelm Röntgen's discovery of X-rays in 1895, when physicians and physicists needed a name for the images those rays produced on photographic plates. Röntgen himself did not use this term. He called his mysterious rays "X-rays" because the unknown quantity was the thing he could not name, and his early images were called "Röntgen rays" or simply "shadow pictures" by many of his contemporaries. "Radiograph" emerged as the more general term for the picture itself, and over time it came to cover images made with other penetrating radiation, not only X-rays.

Synonyms: x-rays
