Question 4: A radiograph shows a clear, unexposed curved edge on one side. What error is this?
- Overlapping
- Double exposure
- Cone cut (Correct answer)
- Reversed film
Correct answer: Cone cut
Cone cuts occur when the PID is not aligned with the receptor, leaving part of the image unexposed.

- Keep the patient's head still
- Improve image contrast
- Protect the thyroid gland from scatter and primary radiation (Correct answer)
- Reduce film fog
Correct answer: Protect the thyroid gland from scatter and primary radiation
The thyroid is radiosensitive, and the collar shields it from scatter radiation during intraoral exposures.

Correct answer: Remove it so it does not appear on the image
Removable appliances can obscure anatomy and create artifacts, so they are removed before exposure.
Question 20: What PPE is generally appropriate for hospital staff treating a contaminated patient?
- Lead apron
- Full self-contained breathing apparatus always
- No PPE needed
- Standard precautions: gown, double gloves, mask, shoe covers (Correct answer)
Correct answer: Standard precautions: gown, double gloves, mask, shoe covers
Standard contact precautions prevent staff contamination; lead aprons do not stop most contamination hazards.
Question 21: A child with primary dentition has closed proximal contacts. Which radiographs are indicated?
- Full mouth series only
- Posterior bitewings (Correct answer)
- No radiographs ever
- Panoramic only for caries
Correct answer: Posterior bitewings
Closed contacts prevent clinical detection of interproximal caries, so bitewings are indicated.

Correct answer: On the opposite side, higher and blurred
Ghost images are projected on the opposite side, higher and larger, due to the beam's upward angle.
Question 52: When should clinical assessment & patient care be conducted in Radiation Health and Safety?
- Only when required by external auditors
- Once during initial setup only
- Only when problems are identified
- At regular intervals and whenever significant changes occur (Correct answer)

- Ionizing radiation travels faster
- Ionizing radiation only comes from radioactive materials
- Ionizing radiation has enough energy to remove electrons from atoms (Correct answer)
Correct answer: Ionizing radiation has enough energy to remove electrons from atoms
Ionizing radiation carries sufficient energy to remove tightly bound electrons from atoms, creating ions; non-ionizing radiation lacks enough energy to ionize atoms.
Question 56: A periapical image shows teeth that appear longer than the actual teeth. What is the most likely cause?
- Film placed backward
- Excessive horizontal angulation
- Insufficient vertical angulation (Correct answer)
- Excessive vertical angulation
Correct answer: Insufficient vertical angulation
Insufficient vertical angulation (beam too flat) stretches the image, causing elongation.
Question 57: Which dental structure appears most radiopaque on a radiograph?
- Pulp
- Dentin
- Cementum
- Enamel (Correct answer)
Correct answer: Enamel
Enamel is the densest, most highly mineralized tissue, so it absorbs the most radiation.
Question 58: Which item should be heat-sterilized between patients?
- The tubehead
- The control panel
- The lead apron
- Reusable film-holding and positioning devices (Correct answer)
Correct answer: Reusable film-holding and positioning devices

Question 60: In which classification do items that contact mucous membranes but do not penetrate tissue fall?
- Critical
- Semicritical (Correct answer)
- Noncritical
- Sterile
Correct answer: Semicritical
Semicritical items touch mucous membranes or non-intact skin and need sterilization or high-level disinfection.
Question 61: Participants changing behavior because they know they are being observed is known as the:
- Hawthorne effect (Correct answer)
- Placebo effect
- Nocebo effect
- Halo effect
Correct answer: Hawthorne effect
The Hawthorne effect is altered behavior due to awareness of being studied.
Question 62: Which timing of vomiting after exposure suggests a higher radiation dose?
- Vomiting after 24 hours
- No vomiting
- Vomiting within 1 hour (Correct answer)

- Terminate the pregnancy
- Administer DTPA immediately
- Stabilize the mother (Correct answer)
- Delay care until the fetal dose is known
Correct answer: Stabilize the mother
Maternal stabilization is the best way to protect the fetus, and dose assessment follows.
Question 64: Which factor BEST indicates mastery of emergency response & critical care in Radiation Health and Safety?
- Years of experience in a single setting

True mastery is demonstrated by the ability to apply knowledge flexibly across different contexts while consistently maintaining quality standards.
Question 65: Why is the beam kept collimated to the receptor size using rectangular collimation?
- It replaces the apron
- It reduces patient dose by limiting tissue exposed (Correct answer)
- It shortens exposure time to zero
- It increases scatter
Correct answer: It reduces patient dose by limiting tissue exposed
Rectangular collimation shrinks the beam to receptor size, reducing tissue irradiated and scatter.
Question 66: Which of the following is considered part of the legal dental record?
- Only the appointment book
- Radiographs, clinical notes, consent forms, and treatment plans (Correct answer)
- Only the patient's photo ID
- Only the billing ledger
Correct answer: Radiographs, clinical notes, consent forms, and treatment plans
The legal record comprises all clinical and consent documentation, including images.
Question 67: In radiology, what is the function of filtration added to an X-ray beam?
- Convert X-rays to visible light
- Remove low-energy photons that would only contribute to dose without diagnostic value (Correct answer)
- Increase patient dose
- Increase beam intensity
Correct answer: Remove low-energy photons that would only contribute to dose without diagnostic value
Added filtration (typically aluminum) removes low-energy X-ray photons that would be absorbed by the patient without contributing to image formation, reducing patient dose.
Question 68: In Radiation Health and Safety, which factor MOST influences the selection of appropriate research methods & evidence-based practice?
- The specific requirements and constraints of the situation (Correct answer)
- The most recently developed technique only
- Personal preference of the practitioner
- Cost as the sole determining factor
Correct answer: The specific requirements and constraints of the situation
The specific requirements and constraints of each situation should drive technique selection to ensure the most effective and appropriate approach.
Question 69: A person who was externally irradiated by a distant source, but has no contamination, poses what risk to rescuers?
- Risk through breath
- Contamination risk through blood
- No radiation risk (Correct answer)
- High gamma exposure risk
Correct answer: No radiation risk
External irradiation does not make a person radioactive, so they can be treated safely.
