RDA Radiology Exam

Determining correct exposure times when different cone (BID) lengths are utilized and minimize exposure is determined by the:

• ALARA principle
• Inverse square law
• Exposure control chart
• KvP time

Time temperature processing means the

• Developing time is determined by the developer temperature
• Fixing time is determined by the developer temperature
• Developing time is determined by the fixer temperature
• Processing time is independent of solution temperature

Digital radiographs are:

• Filmless and require no processing solutions
• The image is captured on a sensor
• The system uses radiation from a tubehead
• All of the above

To reduce cross-contamination, the most appropriate way to store exposed radiographs prior to processing is in:

• Operatory drawers
• Lab coat pockets
• Darkroom cupboards
• Disposable cups

Before exposure to any type of radiographs you must obtain an informed consent from the patient.

• True
• False

How are x-rays produced?

• Sudden stopping of slow speed electrons
• High speed electrons increasing speed
• Sudden stopping of high speed electrons as they collide with a target
• Sudden stopping of slow speed electrons as they collide with a mirror
