Who is ultimately responsible for radiation protection in the imaging team?
Only the patient
Only the radiologist
Hospital administrators
The entire imaging team
The radiographer's primary role in the team is to:
Interpret the image
Schedule appointments
Ensure safe imaging and limit radiation exposure
Prepare prescriptions
Controlling radiant energy involves:
Increasing mAs
Using the imaging system properly to minimize dose
Avoiding collimation
Extending exposure time
Who is responsible for maintaining diagnostic efficacy while protecting the patient?
Radiologist only
Radiographer only
Equipment vendor
Both radiologist and radiographer
The goal of radiation protection is to:
Eliminate radiation entirely
Minimize exposure while obtaining diagnostic quality images
Use as much radiation as possible
Focus only on technologist safety
Radiation protection is based on the principle that:
No dose is too small to matter
Imaging dose cannot be reduced
Some dose is always safe
Protection is unnecessary in modern equipment
Which concept assumes that even small doses may carry risk?
ALARA
Diagnostic efficacy
Pulse fluoro
BERT
The unit for absorbed dose is:
Sievert
Gray
Coulomb/kg
Becquerel
The unit for milligray (mGy) measures:
Biological effect
Exposure in air
Absorbed dose
Radiation activity
The unit millisievert (mSv) refers to:
Radioactivity
Effective dose
Energy of X-rays
Time exposed
Effective dose accounts for:
Only the amount of radiation
Shielding equipment
Repetition of exams
Type of radiation and sensitivity of organs
Which of the following is used to express occupational exposure?
mGy
mSv
Becquerel
Curie
What does absorbed dose refer to?
Energy deposited in tissue
Dose the technologist receives
Total exam time
Output of X-ray tube
Diagnostic efficacy means:
Exposure was high enough
Procedure was inexpensive
Image answered the clinical question
The patient had symptoms
When is a radiologic exam justified?
If it replaces an MRI
When its benefit exceeds the risk
Always, regardless of dose
If the patient requests it
What does ALARA stand for?
A Legal Acronym for Radiation Awareness
As Light As Radiant Air
Always Limit All Radiation Amount
As Low As Reasonably Achievable
Which is NOT part of the ALARA philosophy?
Shielding
Decreasing dose
Increasing time
Optimizing exposure parameters
What are the cardinal rules of radiation protection?
Collimation, filtration, dose
Time, distance, shielding
Dose, field size, shielding
Protocol, contrast, clarity
Which cardinal rule involves spending less time exposed?
Time

Shielding
Rotation
Doubling your distance from the source reduces exposure by:
Half
One-fourth
Double
Ten times
Which method protects patients during exams?
Increasing exposure
Shielding reproductive organs
Removing collimation
Using a longer SID
Patient education about radiation exposure helps:
Create confusion
Increase procedure time
Decrease fear and improve cooperation
Make exams unnecessary
Why is it important to explain procedures to patients?
To reduce panic
To gain informed consent
To build trust
All of the above
What does BERT stand for?
Background Equivalent Radiation Time
Biological Exposure Relative Test
Beam Energy Reduction Technique
Background Equalizing Radiation Time
BERT helps patients by:
Increasing radiation use
Avoiding comparisons

The Image Gently campaign is focused on:
Elderly patients
Technologists
Children
Fluoroscopy equipment
Which campaign encourages dose reduction in adult imaging?
Image Gently
BERT
Shield First
Image Wisely
Image Gently: Step Lightly in fluoroscopy encourages:
Use of higher frame rates

Avoiding motion artifacts
Pause and Pulse encourages:
Speed
Diagnostic failure
Continuous exposure
Better radiation control in pediatric fluoro
What does the NEXT program monitor?
Shielding compliance
Exposure from dental x-rays
Radiation doses from imaging procedures
Equipment quality
Why is NEXT important?
Tracks imaging dose trends
Promotes more exams
Avoids regulations
Ensures higher costs
Dose alert protocols notify:
When exams are completed
If expected dose thresholds are exceeded
When shielding isn't used
If the patient cancels
Dose alerts help radiographers to:
Ignore exposure changes
Limit documentation
Assess whether a dose is justified
Increase technique settings
Protocols for dose alerts are part of:
Radiation therapy
Radiation protection programs
HIPAA regulations
Hospital processes
Which of the following helps reduce repeat exposures?
Poor communication
Fast imaging only
Clear patient instructions
Increased dose
Radiographers demonstrate professionalism by:
Ignoring safety guidelines
Rushing exams
Avoiding communication
Keeping doses low
Children are more sensitive to radiation because:
They move a lot
They have smaller bones
They are louder
They are still growing
A pregnant patient should only be exposed to radiation if:
It's an emergency and benefits outweigh the risks
She requests it
The exam is routine
The technologist isn't sure
Effective dose reflects:
Absorbed dose plus tissue weighting
