Which activity is listed as something that may increase airborne radioactivity?

• A. Painting
• B. Cooking
• C. SANDING
• D. Welding

Answer: (C)

Airborne radioactivity rises when a task creates respirable radioactive dust that can float in the air and be inhaled. Sanding a surface that may be contaminated disturbs the coating and releases fine particles into the air, which can stay suspended and increase internal exposure if inhaled. The other activities listed don’t typically produce this kind of radioactive dust—painting and cooking mostly involve liquids, fumes, or heat, and welding generates fumes and sparks but not necessarily aerosolized radioactive material unless special contaminated materials are involved. To limit this risk, use dust control measures like wet sanding, proper ventilation, and appropriate respiratory protection.
