X-Rey

X-ray (X-ray) is a type of high-energy electromagnetic radiation (like light, but much more energetic) that can pass through many materials, including parts of the human body.

🔬 What is an X-ray?
• X-rays have very short wavelengths and very high frequency compared to visible light. 
• They are invisible to the human eye. 
• They are a form of ionizing radiation, meaning they can remove electrons from atoms and affect cells.

🩻 How X-rays work
• X-ray beams pass through the body.
• Dense materials (like bones) block more X-rays → appear white.
• Soft tissues (muscle, fat, organs) let more X-rays pass → appear gray or dark.

🏥 Main uses

1️⃣ Medicine
• Detect bone fractures
• Check lungs and chest
• Find tumors or infections
• Used in CT scans and other imaging tests 

2️⃣ Other fields
• Airport security scanners
• Industrial inspection (check cracks in metal)
• Scientific research 

⸻

⚠️ Risks
• Because X-rays are ionizing radiation, high or repeated exposure may increase cancer risk.
• Medical use is controlled and usually uses very low doses. 

⸻

📜 History
• Discovered in 1895 by German scientist Wilhelm Röntgen.

If you want, I can explain simply (ELI5 style), or tell about X-ray machine, X-ray test procedure, or side effects.
