  radiograph \ra"di*o*graph\ (r[=a]"d[i^]*[-o]*gr[a^]f), n.
     [Radio- + -graph.]
     1. An instrument for measuring and recording solar radiation.
        [Webster 1913 Suppl.]
  
     2. An image or picture produced upon a sensitive surface, as


        of a photographic or fluorescent plate, by some form of
        penetrating radiation other than light, as X-rays, beta
        rays, etc.; esp., a picture of the internal structure of
        opaque objects traversed by the rays; a skiagraph. When
        the picture is produced upon photographic film by X-rays,
        the picture is usually called an {X-ray photo} or {X-ray}.
        When an image is produced on photographic film by a
        radioactive substance in close proximity to the film, in a
        manner so as to record the spatial distribution of the
        radioactive substance, the resulting image is called an
        {autoradiograph} or {{autoradiogram}}.
