	Autoradiography and fluorography
		Autoradiography is the direct exposure of film by beta particles or gamma rays.
		Fluorography is the exposure of film by secondary light that was generated by the excitation of a fluor or a screen by a beta particle or a gamma ray.
		Note that the image provided by direct autoradiography is always sharper than is the image resulting from fluorography.

	Autoradiography by Jeff Walding
		Autoradiography is a technique that is used to study biochemical processes by labeling sites that contain radioisotopes.
		However, this could prove to be a limitation of autoradiography because often times the size of the silver grain is larger than the organelle, which makes it impossible to identify the exact site of origin (Karp, 1996).
		The technique of autoradiography has proven to be a valuable resource when determining the site of synthesis and the movement of molecules in various biochemical processes.

		Biological autoradiography takes advantage of the fact that animals and plants cannot distinguish between stable and radioactive isotopes of the same elements in their physiological reactions.
		Autoradiography has provided a useful tool in metallurgy, such as in the investigation of the distribution of different metals within an alloy.
		Autoradiography may also be used in studies of frictional damage by machinery.

	Principles of autoradiography
		Autoradiography is a procedure for localizing and recording a radiolabeled compound within a solid sample, which involves the production of an image in a photographic emulsion.
		Direct autoradiography involves placing the sample in intimate contact with an X-ray film, a plastic sheet with a coating of photographic emulsion; the radioactive emissions from the sample produce dark areas on the developed film.
		Indirect autoradiography is a modification in which the emitted energy is converted to light by a suitable chemical (scintillator or fluor).

		The book Art and Autoradiography: Insights into the Genesis of Paintings of Rembrandt, Van Dyck and Vermeer should be viewed as an example of the technique applied to well known paintings, with the art historian, conservator, and museum scientist working together.
		They clearly indicate that “autoradiography by itself cannot be touted as the final word” and describe its use with other complementary methods such as x-ray radiography and analysis of pigment sample cross sections.
		X-ray radiographs show some details lost to autoradiography and the reverse is also true; the authors clearly illustrate that they should be used together whenever possble.

		For $^3$H autoradiography, the efficiency is low, to achieve the highest resolution one must cut thin sections, and high doses and long exposure times are required.
		For $^{14}C$ autoradiography, typical slice thicknesses are 20-30 $\mu$m, which is roughly the achievable rms resolution.
		Behaviors in "freely moving" subjects A problem for both human and animal studies, using autoradiography or non-invasive imaging methods, is the intrusive effect of the system for tracer delivery and scanning.

	History of Autoradiography (Site not responding. Last check: 2007-10-26)
		Autoradiography has a wide range of spatial resolutions; microautoradiography, with resolution down to 0.05 µm, is used to locate tracers within or between cells; macroautoradiography, with resolution of about 50 µm, is used to determine tracer concentration within tissues.
		The first biological experiment involving autoradiography traces the distribution of polonium in biological specimens.
		The use of autoradiography is also proposed for the measurement of ligand binding and drug interaction.

		Autoradiography is a photochemical detection method in which a radioactive sample is placed above a photographic emulsion or film.
		Autoradiography, may be combined with the study of cell physiology by feeding cells specific compounds with radioactive atoms and then microscopically observing on a photographic emulsion the distribution of radioactive events.
		The technique of labeling compounds with radioactive isotopes makes it possible to study the distribution and concentration of isotopes in tissue slices similar to those studied routinely under the microscope.
