CT Scans vs. X-Rays,

When comparing CT scans and X-rays, CT scans are generally more "dangerous" in terms of radiation exposure — but context matters a lot.

💀 Radiation Exposure
X-ray (like a chest X-ray): ~0.1 mSv (millisieverts)

CT scan (like a chest CT): ~7 mSv
→ That's about 70 times more radiation than a single chest X-ray.

TL;DR
✅ X-ray = safer, lower radiation

⚠️ CT = more detailed, but higher radiation

📞 Always ask your doctor: “Is this scan necessary? Are there lower-radiation alternatives?”

Ultrasound or MRI a possible alternative?" (Both use no radiation.)
