Which label color indicates the highest radiation hazard on a package?

Which label color indicates the highest radiation hazard on a package?

• A. Radioactive Yellow-III
• B. Radioactive White-I
• C. Radioactive Red-II
• D. Radioactive Blue-III

Answer: (A)

Color coding for radioactive materials uses a bright yellow background to signal radiation danger, with a number that shows how severe the hazard is. The higher the number, the greater the risk within that yellow category. So the label that communicates the highest level of radiation hazard is Radioactive Yellow-III. Other color schemes or lower numbers (like White-I, Red-II, Blue-III) either belong to different warning systems or indicate lower or different hazards, not the maximum radiation risk.
