The most well known examples of naturally-occurring radionuclides in foods are bananas and Brazil nuts. Bananas have naturally high-levels of potassium and a small fraction of all potassium is radioactive. Each banana can emit . 01 millirem (0.1 microsieverts) of radiation.May 19, 2021

Which foods contain radiation?

• Brazil nuts. pCi* per kg: 12,000. pCi per serving: 240.
• Butter beans. pCi per kg: 4,600. pCi per serving: 460.
• Bananas. pCi per kg: 3,500. pCi per serving: 420.
• Potatoes. pCi per kg: 3,400. pCi per serving: 850.
• Carrots. pCi per kg: 3,400. …
• Red meat. pCi per kg: 3,000. …
• Avocados. pCi per kg: 2,500. …
• Beer. pCi per kg: 390.

What is the most radioactive fruit?

Bananas. Bananas are sufficiently radioactive that they can set off radiation alarms at ports and airports. They offer 1 pCi/kilogram from radon-226 and 3,520 pCi/kilogram from potassium-40. The high potassium content is part of why bananas are so nutritious.

Do you get radiation from eating 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).

What food is the most radioactive?

Brazil nuts are the most radioactive everyday food. However, large quantities of Brazil nuts, lima beans, and bananas all can set off radiation detectors when they pass through shipping. The radiation dose from eating one banana is calculated at 10−7 Sievert or 0.1 microSieverts.

What are 4 examples of radiation?

Radiation Examples

• ultraviolet light from the sun.
• heat from a stove burner.
• visible light from a candle.
• x-rays from an x-ray machine.
• alpha particles emitted from the radioactive decay of uranium.
• sound waves from your stereo.
• microwaves from a microwave oven.
• electromagnetic radiation from your cell phone.

What has the most radiation?

The Most Radioactive Places on Earth

• Uranium: 4.5 billion years.
• Plutonium 239: 24,300 years.
• Plutonium 238: 87.7 years.

Are avocados radioactive?

As the researchers explain, lots of household objects, including foodstuffs, are slightly radioactive because they contain potassium, which is a naturally-occurring radioactive element. Therefore, avocados are technically radioactive because of their high potassium content. That's why bananas are radioactive, too.

Is coffee radioactive?

But did you know your coffee is radioactive, too? It's true. In fact, on a weighted basis, the average coffee powder is roughly three times as radioactive as bananas! If you feel like you're glowing and abuzz after your morning brew, it may not be due to the caffeine…

How much radiation does a phone give off?

The Federal Communications Commission (FCC) — which regulates cell phones, among other things, in the United States — has set radiation standards for cell phones at 1.6 watts per kilogram averaged over 1 gram of tissue.
