Autoradiograph

An autoradiograph is an image produced on a photographic filmby the radiationfrom a radioactivesubstance. In this technique, a compound (such as a metaboliteor DNA) is radiolabeledby a substance that emits either beta radiationor gamma rays. A photographic film is then placed directly on the labelled tissue. This contrasts to techniques such as PETand SPECTwhere the exact localization of the radiation source is provided by careful use of collimators and other devices.

This technique can be used for studies of metabolic activity, and can be used on tissue sections.
