Which of the following is not a valid RCRA characteristic of hazardous waste?

Ignitability
Corrosivity
Reactivity
Radioactivity

The correct answer is: Radioactivity

The correct answer is radioactivity because it is not classified as a RCRA characteristic of hazardous waste. The Resource Conservation and Recovery Act (RCRA) defines hazardous waste based on four specific characteristics: ignitability, corrosivity, reactivity, and toxicity. - Ignitability refers to materials that can easily catch fire. - Corrosivity pertains to wastes that can corrode metals or have a pH of less than 2 or greater than 12.5. - Reactivity describes substances that are unstable or can react violently with water or other materials. These characteristics are essential for determining whether a waste is hazardous under RCRA regulations. Radioactivity, on the other hand, falls under a separate regulatory framework governed by the Atomic Energy Act and is not included in the RCRA hazardous waste definitions. Thus, identifying radioactivity as a characteristic of hazardous waste reflects a misunderstanding of the RCRA criteria.
