# How much radiation is in a banana?

### How much radiation is in a banana?

The radiation exposure from consuming a banana is approximately 1% of the average daily exposure to radiation, which is 100 banana equivalent doses (BED). The maximum permitted radiation leakage for a nuclear power plant is equivalent to 2,500 BED (250 μSv) per year, while a chest CT scan delivers 70,000 BED (7 mSv).

### Which fruit is most radioactive?

Bananas. You probably already knew that bananas are loaded with potassium. But bananas also happen to be one of the most radioactive foods because they contain the isotope potassium-40. Thanks to this isotope, everyone's favorite yellow fruit emits a tiny amount of radiation.

### Are bananas full of radiation?

Bananas are slightly radioactive because they are rich in potassium, and one of its natural isotopes (variants) is potassium-40, which is radioactive. A lorry full of bananas is radioactive enough to trigger a false alarm on a radiation detector looking for smuggled nuclear weapons.

### How many bananas does it take to die from radiation?

10,000,000 bananas Answer by Ramzi Amri, MD, PhD, Physician, on Quora: Yes, you will certainly die from radiation poisoning if you are able to eat 10,000,000 bananas at once. You may also witness chronic symptoms if you eat 274 bananas a day for seven years.

### Can I eat 6 bananas a day?
