Hazardous materials that emit ionizing radiation capable of destroying cells are described as what?

Hazardous materials that emit ionizing radiation capable of destroying cells are described as what?

• A. Radioactive
• B. Thermal
• C. Chemical
• D. Biological

Answer: (A)

Radioactive materials. The key idea is that these substances emit ionizing radiation, which has enough energy to disrupt atoms and break DNA, leading to cell damage or destruction. This is what sets them apart from other hazard types. Thermal hazards involve heat, chemical hazards are about reactive or toxic chemicals, and biological hazards concern organisms or their toxins. So when a substance emits ionizing radiation capable of destroying cells, it’s described as radioactive.
