What are the three categories of radioactive waste?

The correct categorization of radioactive waste includes low-level waste, intermediate-level waste, and high-level waste. This classification is important in the field of radiation safety as it helps determine how each type of waste should be handled, stored, and disposed of, given their varying levels of radioactivity and associated risks.

Low-level waste consists of materials that have low levels of radioactivity and typically includes items like discarded protective clothing, tools, and other materials that have been contaminated. Intermediate-level waste encompasses waste that has a higher level of radioactivity and requires shielding during handling and transportation, often consisting of materials such as reactor components and contaminated machinery. High-level waste, on the other hand, comprises spent nuclear fuel and highly radioactive materials that necessitate extensive shielding and cooling and generally require deep geological disposal to ensure safety.

This structured approach to categorizing radioactive waste is critical for effective waste management and environmental protection in radiation safety practices. The other choices presented do not accurately reflect established categories for radioactive waste and instead refer to terms or classifications that do not apply in this context.
