ASNT Industrial Radiography Radiation Safety Practice Test

What is the maximum transport index for a White transport label?

1. Less than 0.5

2. 1

3. 5 but less than 10

4. 200

The correct answer is: Less than 0.5

The maximum transport index for a White transport label is indeed less than 0.5. White labels, also known as the White-I category, are utilized for package transport that presents a low radiological hazard. The transport index is a numerical value indicating the radiation level at the surface of the package and helps ensure safety during transportation. White transport labels are assigned to packages that either contain no radioactive materials or have very low levels of radioactivity, such that the radiation dose to individuals in proximity is minimal. This designation is crucial for public safety and for those handling the packages during transit. In contrast, the other options propose higher transport indices that are outside the criteria set for White labels and would apply to packages that contain more significant levels of radioactive materials, necessitating different labels and safety measures. For example, a transport index of 1 or greater would typically require a Yellow label, indicating higher radiological hazard and increased precautions.
