Which symbol indicates a radiological hazard?

Which symbol indicates a radiological hazard?

• A. BIO
• B. NUC
• C. RAD
• D. SIG

Answer: (B)

The key idea is how danger signs communicate what kind of hazard you’re dealing with. Radiological hazards are indicated by the radiation trefoil symbol, which points you to ionizing radiation from nuclear sources. In this context, the symbol labeled NUC corresponds to that radiological warning. That’s why it’s the best match—the other labels align with different hazards or generic signs: BIO is for biological hazards, SIG is a general sign, and RAD isn’t the standard radiological symbol used here. So, the symbol for radiological risk is the one labeled NUC.
