ASNT Industrial Radiography Radiation Safety Practice Test

How often must dosimeters and rate alarms be calibrated?

1. Every 6 months

2. Every 12 months

3. Every 18 months

4. Every 24 months

The correct answer is: Every 12 months

The correct answer is that dosimeters and rate alarms must be calibrated every 12 months to ensure accuracy in radiation measurements. Calibration of these devices is crucial because it verifies that they are functioning properly and providing accurate readings of radiation exposure. This is essential for maintaining safety standards in industrial radiography, where precise measurements are necessary to protect personnel from potential overexposure to radiation. Regular calibration also helps in identifying any potential drift in the readings due to environmental factors, wear and tear, or changes in the technology of the measurement devices. By adhering to a 12-month calibration schedule, facilities can ensure compliance with regulatory standards, maintain quality control in their operations, and minimize the risk of radiation-related incidents. While other options suggest longer calibration intervals, they do not align with best practices in radiation safety, which emphasize regular checks to uphold the integrity of radiation monitoring equipment.
