MULTIPLE CHOICE
1. Which Of The Following Are Consequences Of Ionization In Human Cells?
A. Formation Of Unstable Atoms, Free Radicals, And Free Electrons.
B. Disruption Of The Atomic Nucleus, Creation Of Toxic Substances, And Cell Injury.
C. Creation Of Unstable Atoms, Free Radicals, And Damage To Cellular Function.
D. Unstable Atoms, Free Radicals, And Impaired Function Leading To Possible Cell
Death.
ANS: D
Ionization Results In A Series Of Reactions Within The Cell. This Includes The
Formation Of Unstable Atoms, Free Radicals, And The Creation Of Highly Reactive
Molecules, Which Can Lead To Biochemical Changes That Damage The Cell. This Can
Cause A Loss Of Function, Potentially Leading To Cell Death. Ionization Creates
Charged Particles That Damage The Normal Cellular Structure And Function, Which Is
The Foundation For Biological Effects From Radiation.
A: While This Option Is Partially Correct, It Misses The Critical Aspect Of Cellular
Function Impairment.
B: The Term "Disruption Of The Atomic Nucleus" Does Not Accurately Reflect The
Primary Effects Of Ionization At The Cellular Level.
C: While This Is Correct, It Lacks The Full Scope Of Cellular Injury, Which May
Include Both Temporary And Permanent Damage.
Reference: P.4
2. Which Of The Following Types Of Radiation Has Sufficient Energy To Remove
Orbital Electrons From Atoms, Creating Charged Particles?
A. Ionizing Radiation
,B. Nonionizing Radiation
C. Acoustic Radiation
D. Electromagnetic Radiation
ANS: A
Ionizing Radiation Has Enough Energy To Remove Electrons From Atoms, A Process
Known As Ionization, Resulting In Charged Particles (Ions). This Type Of Radiation
Includes X-Rays, Gamma Rays, And Other Forms Of High-Energy Electromagnetic
Radiation. Nonionizing Radiation, In Contrast, Lacks Sufficient Energy To Ionize Atoms.
B: Nonionizing Radiation, Such As Visible Light And Radio Waves, Does Not Have The
Energy To Ionize Atoms.
C: Acoustic Radiation (Such As Ultrasound) Does Not Create Ionization In The Same
Way As Ionizing Radiation.
D: While Electromagnetic Radiation Includes Ionizing Types Like X-Rays And Gamma
Rays, It Also Includes Nonionizing Radiation Such As Visible Light, Which Does Not
Ionize.
Reference: P.5
3. When Patients Are Educated About The Medical Benefits Of Imaging Procedures,
They Are More Likely To:
A. Have Reduced Concerns About Radiation Risk But Still Be Unwilling To Undergo
The Procedure.
B. Choose To Cancel The Procedure Due To Concerns About Potential Harm.
C. Relieve Their Fear Of Radiation But Reject Any Procedure Involving Potential Risk.
D. Understand The Risk-Benefit Balance And Agree To Undergo The Procedure With
Minimal Fear.
ANS: D
Patients Who Are Well-Informed About The Benefits And Potential Risks Of Medical
Imaging Are More Likely To Understand The Risk-Benefit Balance. This Education
Helps Alleviate Radiation-Related Anxiety And Empowers Them To Make Informed
,Decisions, Thus Increasing Their Willingness To Undergo Necessary Procedures Despite
Small Risks.
A: Although Patients May Have Fewer Concerns After Education, This Answer Suggests
They Still Would Not Undergo The Procedure, Which Is Unlikely.
B: Patients Who Understand The Benefits Are Less Likely To Cancel The Procedure
Solely Due To Perceived Risks.
C: While Education Can Reduce Fear, It Does Not Necessarily Lead To Outright
Rejection Of The Procedure When The Benefits Outweigh The Risks.
Reference: P.10
4. The Millisievert (Msv) Is Equal To:
A. 1/10 Of A Sievert
B. 1/100 Of A Sievert
C. 1/1000 Of A Sievert
D. 1/10,000 Of A Sievert
ANS: C
The Millisievert (Msv) Is A Unit Of Dose Measurement Used For Radiation Protection,
And It Equals 1/1000 Of A Sievert (Sv). The Sievert (Sv) Is The SI Unit That Quantifies
The Biological Effect Of Ionizing Radiation. Therefore, The Correct Answer Is 1/1000
Of A Sievert, Which Makes Option C Correct.
A: Is Incorrect Because 1/10 Of A Sievert Is Equivalent To 100 Millisieverts, Which Is A
Larger Dose Than The Millisievert.
B: Is Incorrect Because 1/100 Of A Sievert Equals 10 Millisieverts.
D: Is Incorrect Because 1/10,000 Of A Sievert Equals 0.1 Millisievert, Which Is A Much
Smaller Dose.
The Unit "Msv" Is Crucial For Expressing Radiation Dose In Medical Settings, As It
Allows For Manageable Measurements Of Radiation Exposure That Might Otherwise Be
Difficult To Quantify With Higher Units Like The Sievert.
, 5. The Benefits Of The BERT (Background Equivalent Radiation Time) Method Include:
A. It Does Not Imply Radiation Risk; It Is Simply A Means For Comparison.
B. It Emphasizes That Radiation Is An Innate Part Of Our Environment.
C. It Provides An Answer That Is Easy For The Patient To Comprehend.
D. All Of The Above
ANS: D
The BERT Method Allows For Easy Communication With Patients About Radiation
Exposure By Comparing It To Natural Background Radiation, Which People Are
Exposed To Daily. It Helps Patients Understand That Radiation Is A Natural Part Of Life
And That The Levels Involved In Medical Imaging Are Manageable And Not An
Immediate Risk. Thus, The Correct Answer Is D.
A: Is Only A Partial Answer, As It Doesn’t Capture All Aspects Of The BERT Method's
Benefits.
B: Is True But Doesn't Cover The Full Scope Of The Method’s Advantages.
C: Is Correct But Does Not Account For The Comparison Aspect With Natural
Radiation.
BERT Is A Communication Tool Designed To Reduce Anxiety By Showing That
Medical Radiation Exposure Is Not Extraordinary When Placed In The Context Of
Everyday Environmental Radiation.
6. If A Patient Inquires About The Radiation Dose They Will Receive From A Specific
X-Ray Procedure, The Radiographer Should:
A. Provide An Estimate Based On Comparison To Natural Background Radiation.
B. Avoid Answering By Changing The Subject.
C. Tell The Patient It Is Unethical To Discuss Such Concerns.
D. Refuse To Answer And Suggest They Consult The Referring Physician.
ANS: A
Radiographers Are Trained To Answer Questions About Radiation Exposure By
Comparing The Dose From An X-Ray To Natural Background Radiation. This Allows
