The total transport index of all radioactive material packages in a single vehicle must not exceed what value?

  1. 25

  2. 30

  3. 50

  4. 100

The correct answer is: 50

The total transport index of all radioactive material packages in a single vehicle must not exceed 50. The transport index is a critical safety measure used for the transportation of radioactive materials, as it quantifies the radiation level at a distance of 1 meter from the package. Each package is assigned a transport index based on its activity level and radiation levels. When transporting multiple packages, the total transport index is calculated by summing the transport indices of all individual packages in the vehicle. Regulations stipulate that this total must not exceed 50 to ensure safety during transport, as higher levels could pose significant risks to personnel handling the packages and to the environment. Values lower than 50 may apply depending on specific handling and environmental considerations, but 50 serves as the upper limit for overall safety in transport scenarios involving multiple packages of radioactive materials.
