What is the surface radiation limit for a Yellow II package?

The surface radiation limit for a Yellow II package is established at less than 50 mR/hr. This classification is part of the U.S. Department of Transportation's (DOT) regulations regarding the transport of radioactive materials. Yellow II packages are considered to have a moderate level of radioactive content, allowing for a controlled exposure limit to ensure safety for individuals handling or in proximity to these packages during transport.

This limit is designed to help manage radiation exposure and maintain safety standards for transport workers and the public. By designating a specific limit, it provides a clear guideline for packaging and transport practices, ensuring that appropriate safety measures are in place to minimize risks associated with radiation.

Other options do not align with the established safety regulations for Yellow II packages. The limits for each category of radioactive packaging are in place to create an effective categorization system, helping to manage the risks associated with the transportation of materials that emit ionizing radiation. Understanding these classifications and limits is crucial for anyone involved in nuclear medicine or related fields.
