BED

 The Banana Equivalent Dose (BED) is a fun, informal way to explain how much radiation you’re exposed to by comparing it to eating a banana 🍌

🍌 What’s in a banana?

Bananas contain a small amount of radioactive potassium, specifically Potassium-40, which naturally emits radiation.

📏 Standard value

• 1 banana ≈ 0.1 microsieverts (µSv) of radiation

🔍 Examples for context

Here’s how bananas compare to other common exposures:

• Eating 1 banana → 0.1 µSv
• Flying from London to New York → ~400 bananas
• Chest X-ray → ~1,000 bananas
• CT scan → ~100,000 bananas
• Average daily background radiation → ~100 bananas

⚠️ Important note

The Banana Equivalent Dose is not a precise scientific measurement—it’s just a relatable comparison. Your body tightly regulates potassium, so eating more bananas doesn’t significantly increase your radiation risk.

If you want, I can convert something specific (like a flight or medical scan) into banana equivalents for you.
