reading this section you will be able to do the following:
how an image is produced on a radiograph.
The making of a radiograph requires
some type of recording mechanism. The most common device is film.
A radiograph is actually a photographic recording produced
by the passage of radiation through a subject onto a film, producing
what is called a latent image of the subject.
A latent image is an image
that has been created on the film due to the interaction of radiation
with the material making up the film. This latent image is not
visible to the naked eye until further processing has taken place.
To make the latent image visible the film is processed by exposure
to chemicals similar to that of photographic film.
In the next sub-unit you will learn
about the process of developing film.
- A radiograph
is a image that is produced by the passage of radiation through
a subject onto a piece of film . This produces an latent image
of the subject.
