What is the Transport Index a measure of?

The Transport Index is a crucial measure in the transportation of radioactive materials, indicating the maximum dose rate at one meter from the outer surface of a package containing these materials. It serves as an important safety parameter, providing carriers and personnel handling the package with essential information regarding the potential radiation exposure.

This index is expressed as a numerical value, which helps in ensuring that the transportation of radioactive materials adheres to safety protocols. By understanding the dose rate at a specific distance, individuals can implement appropriate safety measures, such as maintaining a safe distance or utilizing protective equipment, to minimize their exposure to radiation.

The other options do not accurately define the Transport Index: the size of the radioactive material package does not directly correlate with the potential exposure it may pose, the weight of the gauge is unrelated to the radiation risk assessment, and the shipping cost pertains to logistics rather than safety measures regarding radiation exposure. Therefore, the Transport Index specifically focuses on dose rate, highlighting the importance of safety when transporting radioactive materials.
