Autoradiogram \Au`to*ra"di*o*gram\, n. [Auto- + radiogram.]
(Biochemistry)
an image produced upon photographic film by exposure of the
film to a radioactive substance in close proximity to
(usually in contact with) the film.

Note: Recording the distribution of radioactive materials on
an autoradiogram is a technique much used in
biochemical research as part of analytical procedures,
in which radioactively labeled substances are subjected
to a separation process (such as electrophoresis) which
can help to characterize the substance, and the
resulting distribution of the labeled substance is
recorded on an autoradiogram. In microbiology and cell
biology, autoradiograms may be made on the same film as
a photomicrograph, permitting observation of the
distribution of labeled compounds within a cell.

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}}.
