How much radiation can Radioactive 3 packaging transmit at the container level?

The correct answer identifies that Radioactive 3 packaging can transmit radiation at a level of 200 mRem/hour at the container's surface. This classification is part of the packaging hierarchy used in the transportation of radioactive materials, which helps ensure public safety and compliance with regulatory standards.

For Radioactive 3, the limits set for surface radiation levels are designed to reflect the potential hazards associated with higher levels of radioactivity. These levels are established based on the maximum permissible exposure to individuals handling or working near these materials. Understanding these limits is critical for hazardous materials technicians who are responsible for ensuring safety during the handling, transport, and disposal of radioactive substances.

The other options reflect lower radiation transmission levels that are characteristic of packaging with lower classification numbers (such as Radioactive 1 or Radioactive 2), which would not accurately represent the regulatory requirements and safety measures in place for Radioactive 3 packaging. This foundational knowledge about each classification emphasizes the importance of adhering to guidelines to mitigate risks associated with radiation exposure, ensuring that the correct packaging and handling procedures are followed for each level of radioactivity.
