Im surprised you didn't simply use Google for this one.
Radiography refers to the use of ionizing radiation for the acquisition of high quality images for diagnostic purpose, or for the treatment of malignant disease.
In non technical jargon, radiography is the firing of radiation through a person to create an image of the persons inside (guts and bones, etc).
The same radiation can also be used to 'attack' cancers within the body through a similar process in a separate discipline called 'therapeutic radiography'.
radiographies
The two types of autoradiography are in-vivo radiography and in-vitro radiography. These two differ on the method of attaining the visualization of the material.
what is the principal of radiography
Fujifilm pioneered the Computed Radiography technology in 1983, which eventually became the most common in medical diagnostic applications. Fujifilm is the worldwide market leader followed by Agfa & Carestream.
In radiography electrons are emitted when x rays fall on the screen, while in fluoroscopy light is emitted.....the electrons emitted in radiography stabilize the silver ions in the film and hence get deposited as metallic silver.The amount of silver deposition is proportional to the amount of electrons liberated which is in turn proportional to the intensity of the x-rays that strike the film.
ACR is an abbreviation for the American College of Radiography.
radiography
'Direct' radiography implies that the other form is 'indirect' radiography which is indeed the implicit connotation. With digital radiography the results of the X-ray are immediate as the system is connected directly to the computer. In indirect radiography (also called computed radiography) a phosphor plate is used, become radiated, and then are scanned following this exposure to see that X-ray's outcome.

Why radiography is done in industrial engineering & mechanical engineering?
If its medical, i think it maybe an acronym for Computed Radiography or Clinical Research

Encephalogram means radiography of the brain.
When the film is placed within the patient's mouth during radiography, it is known as intraoral radiography. This technique allows for detailed imaging of individual teeth and specific areas within the mouth.
If joint efficiency is 0.7 then there is no radiography,if it is 0.85 then 10% radiography of the total length of welding and if joint efficiency is 1.0 then 100% radiography is required.
