The Correct answer is shielded containers.

Key Points

  • Nuclear wastes are highly hazardous as they emit radioactive radiation that can harm humans, animals, and the environment.
  • To ensure safety, nuclear wastes are stored in shielded containers to prevent the escape of radiation.
  • These containers are made of materials like lead, concrete, or steel, which can block radiation effectively.
  • The shielding prevents the exposure of radiation to workers and the public, ensuring compliance with safety standards.
  • Shielded containers are used during the transportation, storage, and disposal of nuclear waste.
  • This method aligns with international safety guidelines issued by organizations like the International Atomic Energy Agency (IAEA).
  • Proper management of nuclear waste is critical to avoid contamination of soil, water, and air, which could have long-term environmental consequences.
  • Examples of shielded storage systems include dry cask storage systems, where spent nuclear fuel is stored in shielded casks on-site at nuclear power plants.

 Additional Information

  • Bottles
    • Storing nuclear waste in bottles is not a viable option due to their lack of radiation shielding.
    • Bottles are primarily made of materials like glass or plastic, which cannot block radioactive emissions effectively.
  • Dustbins
    • Dustbins are used for regular waste disposal and are not designed to handle or contain radioactive materials.
    • They lack the necessary features like shielding and sealing required for safe nuclear waste management.
  • Open containers
    • Open containers pose serious safety risks as they allow radioactive emissions to escape into the environment.
    • Such methods are highly unsafe and are not permitted under nuclear waste management regulations.
