ADAP Radiography 3

Question 1

What is the ALARA principle in dental radiography?

Accepted Answer

As Low As Reasonably Achievable

Answer

ALARA stands for As Low As Reasonably Achievable and guides practitioners to minimize radiation exposure while still obtaining diagnostic-quality images.

Question 2

Which of the following is a characteristic of a digital radiographic sensor compared to traditional film?

Accepted Answer

Provides an immediate image on a computer monitor

Answer

Digital sensors display the radiographic image almost instantly on a computer monitor, eliminating darkroom processing time.

Question 3

What is the function of the fixer solution in traditional film processing?

Accepted Answer

Removes unexposed silver halide crystals and hardens the emulsion

Answer

Fixer removes unexposed and undeveloped silver halide crystals from the emulsion and hardens the gelatin, making the image permanent and stable.

Question 4

Which radiographic error results from the X-ray beam not being centered on the receptor, cutting off part of the image?

Accepted Answer

Cone cutting

Answer

Cone cutting occurs when the PID (position-indicating device) is misaligned and the X-ray beam misses part of the receptor, leaving a clear unexposed area on the processed image.

Question 5

What does milliamperage (mA) control in an X-ray unit?

Accepted Answer

The quantity (number) of X-rays produced per unit time

Answer

Milliamperage controls the amount of current flowing through the X-ray tube filament, which determines the number of electrons available to produce X-rays (quantity).
