Which finding would you expect with moderate radiation exposure?

• A. Fever and dehydration
• B. Nausea and vomiting
• C. Bleeding gums
• D. Hair loss and first-degree burns

Answer: (D)

Radiation injures rapidly dividing cells, so the skin and hair follicles are among the first tissues to show damage as the dose increases. At moderate exposure, the most consistent signs are hair loss (alopecia) in exposed areas and mild skin injury described as first-degree burns, which reflect superficial epidermal damage and erythema. These cutaneous effects arise before more extensive, systemic issues. Higher doses would produce broader problems like significant nausea, vomiting, fever, dehydration, or bleeding gums due to bone marrow suppression. So hair loss with mild skin burns aligns with a moderate exposure level, making it the best fit for this scenario.
