What does the term 'mixed waste' refer to?

The term 'mixed waste' refers specifically to a combination of hazardous and radioactive waste. This definition is essential in radiation safety and environmental management domains because it addresses the complexities and challenges associated with handling and disposing of such waste. Mixed waste requires careful regulation and management due to the dangers posed by both the hazardous materials and the radioactive components, which necessitate different handling procedures and disposal methods.

Understanding this term is crucial for ensuring safety and compliance in facilities that manage materials posing both chemical and radiological hazards. The other options target different types of waste that do not incorporate the specific combination of hazardous and radioactive characteristics, hence they do not capture the essence of what 'mixed waste' truly entails.
