What should you refer to in order to control the distance for packages labeled 'radioactive II' or 'radioactive III'?

The transport index and the separation distances are key components in determining the control of distance for packages labeled 'radioactive II' or 'radioactive III.' The transport index specifically provides crucial information about the level of radiation emitted from the package and helps in assessing the safe distance that should be maintained to protect personnel and the public from exposure.

The separation distances serve as guidelines that specify how far these radioactive packages should be kept from unprotected individuals and sensitive environments, based on their transport index values. By combining the information from both the transport index and the separation distances, one can effectively manage safety measures and ensure compliance with regulations regarding the transport of radioactive materials. This dual approach is essential for maintaining safe transport and minimizing health risks associated with exposure to radiation.

Other options, such as hazard communication standards or shipping documents, while important in their own contexts, do not provide the specific guidance needed to control the distance based on radiation levels for the packages in question.
