Abstract: As an important indicator to the safety in the transportation of radioactive materials, the determination of Transport Index is a key task. However, due to the diversity of packages, there are often misunderstandings in the actual transportation activities. Class I surface contaminated object and its amplification coefficient are discussed with examples, to provide a reference to a more rational use of Transport Index and the amplification coefficient, so as to ensure the transport safety of radioactive materials.

Key words: Radioactive material, Transport, Transport index, Amplification coefficient
