Examples of class 7 radioactive materials can include:

• A. Nuclear waste, radioactive medical materials, and X-ray equipment
• B. Coal and wood
• C. Plastic bottles
• D. Fresh fruit

Answer: (A)

Class 7 covers materials that emit ionizing radiation or contain radioactive substances. The best example set includes nuclear waste, radioactive medical materials, and X-ray equipment because each involves actual radioactive content or radiation sources. Nuclear waste remains highly radioactive and is shipped as radioactive material. Radioactive medical materials encompass radiopharmaceuticals and sealed sources used for diagnostics or therapy, which are tightly regulated as Class 7. X-ray equipment can contain sealed radioactive sources used in some imaging devices, so it falls under the same hazardous category. The other items—coal and wood, plastic bottles, and fresh fruit—do not inherently contain or emit significant radioactive material, so they are not classified as Class 7.
