ASNT Industrial Radiography Radiation Safety Practice Test

How often should radiation survey equipment be calibrated?

1. Monthly

2. Quarterly

3. Semiannually

4. Annually

The correct answer is: Semiannually

Calibration of radiation survey equipment is crucial to ensure accuracy and reliability in measuring radiation levels. Regular calibration helps detect any drifts in instrument performance over time due to factors like wear and environmental conditions. Semiannual calibration is a widely accepted standard in many regulatory and industry guidelines because it strikes a balance between ensuring the instrument’s accuracy and managing resources effectively. By calibrating survey equipment every six months, facilities can maintain high safety standards and provide adequate protection for personnel from radiation exposure. This frequency allows enough time to monitor instruments for any potential issues while ensuring compliance with safety regulations and protocols. Proper calibration frequency also helps in preemptively identifying problems that could arise from equipment malfunction or degradation.
