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.
How much radiation is in a banana?
A banana contains about 450 mg of potassium, and when eaten exposes the consumer to about 0.01 mrem due to its K-40 content.
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.
Are bananas toxic?
Bananas are not dangerous ” and in fact they are, and always have been, very good for you.” Adults should consume about 3,500mg of potassium per day, according to the UK’s National Health Service.
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.
Which foods contain radiation?
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.

Broccoli is known to have a low level of natural radiation. It isn’t dangerously radioactive, and no one is going to die from the imported legume, unless the salad chef has something up his sleeve.
Can u eat too many bananas?
Eating too many bananas may have detrimental health effects, such as weight gain, poor blood sugar control, and nutrient deficiencies.
Why are bananas not good for you?
Bananas are a sugary fruit, so eating too many and not maintaining proper dental hygiene practices can lead to tooth decay. They also do not contain enough fat or protein to be a healthy meal on their own, or an effective post-workout snack. Eating bananas becomes significantly risky only if you eat too many.
Is 2 bananas a day too much?
As we’ve mentioned, most Americans are deficient in potassium, and two whole bananas a day won’t provide your full RDA. You’d need to eat 7 or 8 bananas to get enough daily potassium from that source alone. However, too much potassium is just as dangerous as too little ” it can destroy your heart muscle, for one.

Why are Brazil nuts radioactive?
They consist of a significant amount of radium that contributes to their radioactivity. Brazil nuts (especially the ones grown in Brazil) grow on trees that have deep roots, which reach into the soil to produce high amounts of natural radium, a source of radiation.
Who should avoid bananas?
Bananas are higher in calories than other fruits-at about 105 calories-and they have less fiber, so you won’t feel full as long. A banana might be a good snack, but for calorie counters, there are better snacks out there. They are mid-level on the glycemic index, so diabetics may want to avoid them.

Is non ionizing radiation harmful?
RF energy is a type of non-ionizing radiation. Non-ionizing radiation is not strong enough to directly affect the structure of atoms or damage DNA; however, it does cause atoms to vibrate, which can cause them to heat up. When RF energy is very strong, such as from radar transmitters, it can be dangerous.
