ASNT Industrial Radiography Radiation Safety Practice Test

Which personnel monitoring devices are mandatory before performing radiography?

1. Survey meter and TLD only

2. Survey meter, dosimeter, and film badge/TLD

3. Operating rate alarm and film badge only

4. Survey meter and alarm only

The correct answer is: Survey meter, dosimeter, and film badge/TLD

Before performing radiography, it's essential to ensure that personnel monitoring devices are properly utilized to safeguard against radiation exposure. The correct answer encompasses a comprehensive approach to monitoring personnel. A survey meter is critical for measuring radiation levels in the environment, allowing workers to assess potential exposure and ensuring that they are not in a hazardous area when radiography is being conducted. The dosimeter, which measures an individual’s cumulative radiation exposure over time, is essential as it provides personal monitoring. Film badges or thermoluminescent dosimeters (TLDs) serve a similar purpose by providing a record of exposure. Thus, using all three devices ensures maximum safety and compliance with regulatory requirements. The absence of any one of these devices can lead to inadequate monitoring of radiation exposure, increasing the risk of overexposure to personnel. The use of this combination of devices is in line with industry best practices and regulatory standards to ensure that all personnel involved in radiography are adequately monitored and protected from harmful radiation levels.
