ASNT Industrial Radiography Radiation Safety Practice Test

According to the regulations, a Yellow II shipping container must have what maximum surface reading?

1. Less than 50 mR/h

2. Less than 100 mR/h

3. Less than or equal to 200 mR/h

4. More than 50 mR/h

The correct answer is: Less than 50 mR/h

For a Yellow II shipping container, the maximum surface reading allowed is less than 50 mR/h. This classification is important in the context of transporting radioactive materials, as the regulations established by the Department of Transportation (DOT) and the International Atomic Energy Agency (IAEA) are designed to ensure safety during the transport process. The Yellow II designation is indicative of a container that can accommodate certain levels of radioactive materials while still complying with safety standards for radiation exposure. The limit of less than 50 mR/h is intended to minimize the radiation dose to individuals who might be in proximity to the container during shipping and handling. It strikes a balance between transport efficiency and safety, ensuring that the risk of radiation exposure is kept within acceptable bounds for both shipping personnel and the public. Establishing this maximum surface reading is part of a broader framework that includes labeling, packaging, and handling procedures designed to maintain safety when dealing with radioactive materials. Understanding these regulations is critical for compliance and for minimizing health risks associated with radiological exposure during the transportation of hazardous materials.
