    I’ve had several scans and worry about total radiation. ☢️ How much is too much?

    Radiation dose: understanding cumulative exposure

    Talking points

    Source Rough dose
    Chest x-ray 🫁 Low, ~0.1 mSv
    CT scan 🖥️ Higher, ~2–10 mSv
    Natural background 🌍 ~3 mSv/yr
    Reassurance ✅ Doctors weigh benefit vs risk
    • Ask why scan is needed
    • Keep records
    • Don’t refuse needed care

    How do you track your imaging history? 📋
