Question: 1 / 400

Which of the following statements about "Radioactive" labels is true?

Yellow III indicates the highest level of radioactivity

The statement that Yellow III indicates the highest level of radioactivity is true. The labeling system for radioactive materials consists of three categories, with each category being represented by a different color and number. Yellow I indicates low-level radioactivity, Yellow II indicates medium-level radioactivity, and Yellow III denotes the highest level of radioactivity. The use of Yellow III signifies that the material poses a greater risk and therefore requires stringent handling and transportation protocols to ensure safety.

Understanding this labeling is crucial for those involved in the transport of hazardous materials, as it allows for immediate recognition of the potential danger associated with radioactive substances. Knowing the implications of these labels helps in adhering to safety regulations and ensuring that appropriate protective measures are in place.
