ASNT Industrial Radiography Radiation Safety Practice Test

Which feature is crucial in the operation of a survey meter?

1. Visual monitoring only

2. Adjustable sensitivity settings

3. Calibrated accuracy for each scale

4. Compact design for easy transport

The correct answer is: Calibrated accuracy for each scale

The feature of calibrated accuracy for each scale is crucial in the operation of a survey meter because it ensures that the meter provides reliable and precise measurements of radiation levels. Each scale on a survey meter is designed to measure different ranges of radiation intensity, and proper calibration is essential to guarantee that the readings are accurate within those ranges. Calibration accounts for variations in instrument response and environmental factors, allowing users to trust the measurements when assessing radiation exposure or contamination. Without calibrated accuracy, a survey meter could provide misleading information, potentially leading to unsafe conditions during radiographic operations or improper handling of radioactive materials. Accurate readings are vital for maintaining safety protocols and ensuring compliance with radiation safety regulations.
