Which of the following is a sign of overexposure to radiation?

• A. Tooth decay
• B. Skin burns and hair loss
• C. Teeth sensitivity
• D. Headaches

Answer: (B)

Skin burns and hair loss are clear indicators of overexposure to radiation due to the biological effects of high doses of ionizing radiation on human tissues. When a person is exposed to radiation levels that exceed safety thresholds, the skin and hair follicles can suffer damage. This can manifest as burns on the skin, which might present as redness, blistering, or peeling, depending on the severity of the exposure. Hair loss can occur because the rapidly dividing cells in hair follicles are particularly susceptible to radiation damage. High doses of radiation can disrupt normal cellular processes, leading to the loss of hair as the follicles fail to regenerate hair properly. In contrast, while tooth decay, teeth sensitivity, and headaches can stem from various dental or health issues, they are not direct signs of radiation overexposure and typically arise from other factors such as poor oral hygiene, dental disease, or stress rather than radiation effects.
