What type of packages are designed to transport radioactive materials with low radioactivity?

The correct answer pertains to the use of steel, wood, or fiberboard packaging for the transportation of radioactive materials with low radioactivity. This type of packaging is designed to meet specific regulatory standards for safety and containment while being effective at shielding low levels of radiation.

Steel provides exceptional structural integrity and durability, ensuring that the package can withstand physical stresses during transportation. Wood and fiberboard offer lighter alternatives that still meet containment requirements, especially for materials of lower radioactivity where lighter, less expensive packaging can be utilized without sacrificing safety.

In contrast, wooden crates, while sturdy, may not have the rigorous design standards for radiation containment compared to specialized packaging. Plastic containers can lack the necessary durability for heavy or potentially hazardous materials and may not provide adequate radiation shielding. Glass bottles, while they can be used for some hazardous materials, do not typically meet the requirements for transporting radioactive materials since they can break easily and are not suited for high-stress environments.
