• Subject contrast and film contrast are the two factors that comprise radiographic:
• The range of the specimen thickness that can be adequately recorded on a radiograph is known as the of the radiograph.
• The ‘multi-film’ technique may be used when one radiograph film does not have enough to produce a satisfactory radiograph of a specimen.
• Contrast is defined as the comparison between on different areas of the radiograph:
• The approximate radiographic equivalence factors for steel and copper at 220 kV are 1.0 and 1.4 respectively. If it is desirable to radiograph a 1.27 cm (0.5 inch) piece of copper, what thickness of steel would require about the same exposure characteristics?
• Use of a slower speed film improves the definition of the radiograph because the slower film:
• Definition is defined as the measure of the of the outline of the image in the radiograph.
• Source-to-object distance, object-to-film distance, and source size are the three factors that control the of the radiograph.
• A radiograph is made using film X with an exposure of 10 mA-min. Film density obtained in the area of interest is 1.0. If it is desired to achieve a density of 2.0 in the area of interest, what exposure is required? (Log relative exposure = 1.1 for a density of 1.0 and 1.62 for a density of 2.0)
• A dark, jagged, linear indication appears on a radiograph of a casting. The area is a transition area between a thick and a thin section. This indication should be interpreted as:
