A hazmat class for material containing radionuclides?

• A. Class Seven - Radioactive Material
• B. Class Two - Gases
• C. Class Three - Flammable Liquids
• D. Class Five Oxidizing Substances and Organic Peroxides

Answer: (A)

Radionuclides are radioactive materials, so they belong to the class that covers radioactive substances. In hazmat classifications, that is Class Seven. The other options describe gases, flammable liquids, and oxidizing substances, which are unrelated to radioactivity, so they don’t fit for materials containing radionuclides. When shipping, radioactive materials require Class Seven handling, with the specific packaging, labeling, and documentation rules that go with that category.
