Texas Industrial Radiographer Certification ACTUAL EXAM
COMPLETE QUESTIONS AND CORRECT ANSWERS LATEST
UPDATE THIS YEAR
SHORT POINT-FORM COVERAGE
• ALARA = reduce time, increase distance, use shielding
• Always survey before, during, after exposure
• Verify source is fully retracted
• Never leave exposure area unattended
• Follow Texas regulations strictly
• Wear and monitor dosimeter correctly
• Report all abnormal readings and incidents
• Maintain secure boundaries and warning signs
• Inspect equipment before use
• Accurate documentation is legally required
50 SCENARIO-BASED MCQs (1–50)
, Page 2 of 90
1.
While conducting a radiographic exposure, the radiographer notices that the survey meter indicates
radiation levels higher than expected near the boundary. What should be the immediate action?
A. Continue the exposure and finish quickly
B. Stop the exposure and reassess the boundary immediately
C. Ignore since boundary is already marked
D. Turn off the survey meter
Answer: B
Rationale: Unexpected high readings indicate unsafe conditions; exposure must stop and area
reassessed.
2.
A radiographer reduces the exposure time by half but does not change distance or shielding. How does
this affect radiation dose received?
A. Dose doubles
B. Dose remains unchanged
C. Dose is reduced proportionally
D. Dose becomes zero
, Page 3 of 90
Answer: C
Rationale: Exposure is directly proportional to time; reducing time lowers dose.
3.
During setup, a radiographer fails to verify that the radioactive source has fully retracted after exposure.
What is the primary risk?
A. Equipment malfunction
B. Continued radiation exposure to workers
C. Documentation error
D. Reduced image quality
Answer: B
Rationale: An unretracted source continues emitting radiation, posing serious hazard.
4.
A trainee attempts to perform radiography without direct supervision from a certified radiographer.
What regulation is violated?
A. Equipment safety regulation
B. Texas supervision requirements
C. Transportation rules
D. Documentation standards
, Page 4 of 90
Answer: B
Rationale: Trainees must always be supervised per Texas regulations.
5.
A radiographer doubles their distance from a radiation source. According to the inverse square law,
what happens to exposure?
A. It doubles
B. It halves
C. It becomes one-fourth
D. It remains unchanged
Answer: C
Rationale: Exposure decreases by the square of the distance increase.
6.
A radiographer notices their dosimeter reading unusually high early in the shift. What is the most
appropriate action?
A. Ignore until shift ends
B. Stop work and report immediately
C. Remove the dosimeter
D. Continue working
