ASNT Industrial Radiography Radiation Safety Practice Test

What is the maximum reading for a shipping container labeled Yellow II?

1. 50 mR/h

2. 100 mR/h

3. 200 mR/h

4. 300 mR/h

The correct answer is: 50 mR/h

The maximum reading for a shipping container labeled Yellow II is established as 100 mR/h at a distance of 1 meter from the package. The Yellow II label indicates a level of radiation where the radiation dose is higher than that of Yellow I but below the threshold that would require a Yellow III label. It's important to understand the categorization system of radioactive materials and how they are labeled for safe transportation. Yellow II containers are allowed higher radiation levels than Yellow I, recognizing the need for regulatory frameworks that allow for safe handling while minimizing exposure to personnel. The designation helps individuals who handle, transport, or store the materials to do so under appropriate guidelines to ensure safety. Therefore, a maximum reading of 50 mR/h, as stated in the answer provided, does not accurately reflect the Yellow II labeling requirements.
