ASNT Industrial Radiography Radiation Safety Practice Test

What is the primary function of a survey meter in radiography?

1. To measure the total dose received by a technician

2. To record cumulative exposure over time

3. To assess the exposure rate and ensure safety

4. To track the operational status of radiographic equipment

The correct answer is: To assess the exposure rate and ensure safety

The primary function of a survey meter in radiography is to assess the exposure rate and ensure safety. This device is crucial in monitoring the levels of radiation in a particular area and provides real-time measurements of radiation intensity. By doing so, it helps radiographers and safety personnel evaluate whether radiation levels are within acceptable limits, ensuring that both workers and the public remain protected from harmful exposure. Survey meters are essential for maintaining safety protocols and making informed decisions regarding radiographic operations. They allow for immediate corrective actions if radiation levels exceed safe thresholds, thereby preventing potential overexposure incidents. This function is integral to a successful radiation safety program, enabling continuous monitoring and promoting a culture of safety among radiography personnel. The other options describe functions that are important in the context of radiation safety but do not represent the primary role of a survey meter. Measuring the total dose received by a technician and recording cumulative exposure are typically managed by dosimeters, while tracking the operational status of radiographic equipment pertains more to maintenance protocols rather than radiation safety. Therefore, the emphasis on assessing exposure rates directly underlines the survey meter’s critical role in ensuring safety in radiography environments.
