Quality Assurance and Quality Control in Radiography

Flashcards covering vocabulary terms related to Quality Assurance and Quality Control in Radiographic Darkroom Procedures.

Darkroom

An enclosed area or chamber intentionally lightproof, used for handling and processing films in radiography.

Photosensitive Crystals

Crystals in film emulsions that are sensitive to visible light and can be fogged by any light leaks.

Lead Shielding

Walls adjacent to radiographic rooms should be shielded with the correct thickness of lead to protect staff and materials.

Dry Bench

Surface where cassettes are unloaded and recharged with fresh film, should be splash-free.

Wet Bench

Area where the films are processed, typically containing tanks for developer, rinse water, and fixer.

Processing Chemicals

Solutions like developer and fixer used to develop radiographs; critical for converting latent images to manifest images.

Safe Light

A light that allows low levels of illumination without fogging film, typically using colored filters.

Film Cassette

A device that holds x-ray films and intensifying screens in contact.

Radiographic Film Sizes

Standard sizes for radiographic films, including dimensions like 14x17 and 10x12 inches.

Humidity Control

Maintaining relative humidity at 30-60% for optimal functioning of film and darkroom equipment.

Air Conditioning

A system that provides satisfactory working conditions for staff by maintaining room temperature and air circulation.

Film Storage

Proper storage practices to prevent damage to films, including upright positioning and temperature control.

Washing Process

Step in film processing that removes fixer from the film emulsion to ensure archival quality.

Static Electricity

A risk in the darkroom due to materials and surroundings; measures like grounding surfaces are recommended to minimize it.

Ventilation

The process of ensuring sufficient air exchange to maintain comfort and effectiveness of film processing.
