Radioscopy- Radioscopy is a nondestructive testing

technique that uses penetrating radiationto produce images viewed duringirradiation.

- Radioscopic imaging and real timeradiography mean the same as radioscopy

- Traditional radiography uses flm as theimaging medium, radioscopy uses as

uorescent screen to convert radiation tolight or direct viewing or electronicimaging.

- Fine grain, thinner coatings provide higherresolution but lower light output

- ight e!ciency is lower or higher energyradiation
