ASNT Industrial Radiography Radiation Safety Practice Test

How often must dosimeters be calibrated?

1. Every six months

2. Annually

3. Every two years

4. Every five years

The correct answer is: Annually

Dosimeters, which are devices used to measure exposure to ionizing radiation, must be calibrated regularly to ensure their accuracy and reliability. The calibration process involves comparing the readings from the dosimeter to a known radiation source to adjust for any discrepancies that may occur over time. calibrating dosimeters annually is a standard practice in the field of radiation safety. This frequent calibration ensures that any potential drift in the accuracy of the dosimeter is identified and corrected in a timely manner. Annual calibration helps maintain compliance with safety regulations and ensures that personnel monitoring is precise, which is critical for the protection of workers in environments where radiation exposure may occur. Calibration intervals can vary depending on regulatory requirements, the type of dosimeter, and usage conditions, but an annual schedule is commonly adopted for maintaining optimal safety and measurement accuracy in industrial radiography. This regular maintenance is crucial for effective monitoring of radiation exposure and compliance with safety standards.
