Hazard Class 7 – Radioactive materials

For DOT requirements, radioactive material means any material having a specific activity greater than 0.002 microcuries per gram (µCi/g). The specific activity of a radionuclide means the activity of the radionuclide per unit mass of that nuclide. The specific activity of a material in which the radionuclide is essentially uniformly distributed is the activity per unit mass of the material.

Examples

• Radioactive material, Type B(U) package, fissile
• Radioactive material, uranium hexafluoride, fissile
• Radioactive material, Type B(M) package, fissile
• Radioactive material, Type A package, special form, fissile
• Radioactive material, excepted package-empty packaging
