What type of package is indicated by a Yellow II designation?

A package designated as Yellow II is categorized under the U.S. Department of Transportation's regulations for the transport of radioactive materials. This designation indicates that the package has a moderate radiation capacity for transport. Specifically, Yellow II packages are designed to protect against radiation exposure for individuals handling or transporting radioactive materials, as they provide a controlled level of radiation exposure.

The Yellow II labeling signifies that the dose rate at the surface of the package does not exceed a certain limit, which reflects a controlled environment where the radiation is managed to minimize risk. This is especially important in the context of transporting items that may contain radioactive materials, ensuring that safety protocols are upheld throughout the transportation process.

Understanding the levels of radiation capacity, like Yellow II, is essential for professionals dealing with radioactive materials, as it directly affects how materials should be handled, the precautions necessary during transport, and the overall safety of both handlers and the general public.
