    Radiation Sickness

    Radiation Sickness

    Radiation sickness (also called acute radiation syndrome) happens when a person is exposed to large amounts of radiation all at once.

    Exposure to small amounts of radiation?like from an X-ray or CT scan?doesn't cause any symptoms. But exposure to large amounts of radiation all at once?like from a nuclear accident?may cause radiation sickness and death.

    Symptoms of radiation sickness may include:

    • Nausea, vomiting, and diarrhea.
    • Fever.
    • Fatigue.
    • Feeling weak, faint, or dizzy.
    • Hair loss.
    • Skin redness, itching, swelling, or burns.
    • Pain.
    • Seizures.

    People who have been exposed to large amounts of radiation and have these symptoms need to see a doctor right away.
