What does the vertical stripe marking indicate on such packaging?

• A. radioactive levels
• B. Hazard Class
• C. maximum radiation levels
• D. number of radioactive atoms

Answer: (A)

Vertical stripe markings on packaging with radioactive material act as a quick visual cue of the radiation emitted by the package. They are used to indicate the dose rate or radiation level at the surface, helping responders judge how much protection, time, and distance are needed. This is about how much radiation is being emitted, not about the type of hazard class, the total number of atoms, or a pre-set maximum level. The actual hazard class for radioactivity is shown by the standard symbols and class labeling, while the stripes give you an immediate sense of how intense the emission is so you can plan safety actions accordingly.
