ASNT Industrial Radiography Radiation Safety Practice Test

How often must survey meters be calibrated?

1. Every month

2. Annually

3. Every six months

4. Every two years

The correct answer is: Every six months

Survey meters used in radiography must be calibrated regularly to ensure accuracy and reliability in measuring radiation levels. The calibration frequency is important because it helps in maintaining the instrument's precision, thereby ensuring that it provides correct readings that are critical for safety measures in radiography work environments. The correct answer indicates that survey meters should typically be calibrated every six months. This timeframe strikes a balance between ensuring ongoing accuracy and managing operational efficiencies, considering the potential wear and tear on the instrument due to frequent usage or environmental factors. Regular calibration, as specified, is vital for complying with safety standards and regulations, thus helping to minimize risks associated with radiation exposure. Calibration intervals can vary based on organizational policies, manufacturer recommendations, and applicable regulatory requirements. In this context, calibrating every six months aligns with established practices in the industry to maintain stringent safety and accuracy standards.
