Which statement best describes radioactive waste?

• A. Non-radioactive items that can be discarded with regular trash.
• B. Radioactive waste that can be left in place indefinitely if not used.
• C. Items that generate heat but are safe to leave in place.
• D. Radioactive material that must be disposed, if you come in contact you may be contaminated.

Answer: (D)

Radioactive waste is material that has become contaminated with radioactive material or contains unwanted radionuclides and must be managed and disposed of under radiation safety rules. This is the core point workers need to remember: disposal is required to prevent exposure and the spread of contamination. If you come into contact with contaminated items, you can transfer radioactive material to yourself or to surfaces, clothing, or other people, which is why these items must be handled with proper containment, labeling, and disposal procedures rather than treated as regular trash. The other ideas aren’t correct because non-radioactive items can go to regular trash, leaving waste in place indefinitely isn’t allowed under safety programs, and heat generation alone doesn’t define radioactive waste—many wastes don’t heat up but still require proper disposal due to contamination.
