ASNT Industrial Radiography Radiation Safety Practice Test

What is the maximum transport index for a Yellow III transport label?

1. 1

2. 5 but less than 10

3. 10

4. 200

The correct answer is: 5 but less than 10

The maximum transport index for a Yellow III transport label is defined as "5 but less than 10." This classification applies to radioactive materials that pose a significant hazard during transport and require specific safety precautions. The transport index is a crucial part of the labeling system used to inform handlers and transporters about the potential radiation exposure levels associated with a package containing radioactive material. For a Yellow III label, the index indicates that the package could produce a radiation dose rate between 5 and 10 millirem per hour at a distance of one meter from the package. Understanding these classifications is essential for ensuring the safety of personnel involved in the handling and transport of radioactive materials, as it helps to establish the necessary safety measures to minimize exposure.
