Which safety precaution is commonly recommended during radiation surveys?

• A. Don't eat, drink, or smoke
• B. Don't take unnecessary risks
• C. Follow command guidance
• D. Wear protective gloves

Answer: (A)

Preventing ingestion of radioactive material is crucial during radiation surveys. Contamination on skin or surfaces can be carried to the mouth if you eat, drink, or smoke in the area, delivering radionuclides directly into the body and increasing internal dose. By not bringing food or drinks into the survey zone and avoiding tobacco use there, you dramatically reduce the main route of internal contamination. Other safety practices like following established procedures or using gloves are important, but the action that directly minimizes internal exposure in this context is to avoid eating, drinking, or smoking in the area.
