TWO CLASSIFICATIONS OF ARTIFACTS

Sensitized artifacts:
• Artifacts result from any type of exposure that sensitizes the emulsion/
• Static electricity, pressure, extraneous radiation.

Non-sensitized artifacts:
• Artifacts result from physical damage to the film.
• Dirt deposits, scratches.
GENERAL RADIOGRAPHIC TIME PERIOD IN WHICH ARTIFACTS OCCUR
1. During radiographic exposure.
2. During processing of the film.
3. When the film is being handled and stores either before or after processing.

Radiographic Cassette:

A thin light- tight container, slightly larger that the film it is intended to hold.

2 Major Parts of the Cassette

The front Cover – usually made of Carbon Fiber and other plastic materials. This must be rigid and durable but radiolucent. This is made of materials with low atomic number so that it [...]

1.) In handling radiographic film be careful not to bend, crease, or otherwise subject it to rough handling.
2.) Clean hands are a must, and hand lotion and cream should be avoided.
Artifacts – the marks or spurious images that sometimes appear on the processed radiograph.
• Heat and Humidity
Heat – reduces contrast and increases fog of a radiograph.
