Some potassium is always taken in via the diet, and some is always excreted, meaning that there is no buildup of radioactive potassium. So, while bananas are indeed radioactive, the dose of radioactivity they deliver does not pose a risk.
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, everyones favorite yellow fruit emits a tiny amount of radiation.
Do bananas give off radiation?
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. This is a very small amount of radiation.
How many bananas is equal to Chernobyl?
Exposure from eating a banana is estimated at between 0.09-2.3 microSieverts. Lets use a figure of 0.1 microSievert per banana. Thus, exposure from Chernobyl and Fukushima equates to 6,480,000,000,000 Banana Equivalent Doses – thats 6.48 trillion bananas or, if you prefer, 6.48 terabananas or 6,480 gigabananas.

Is it OK to eat 2 bananas a day?
Bananas are one of the most popular fruits in the world. Theyre full important nutrients, but eating too many could end up doing more harm than good. Too much of any single food may contribute to weight gain and nutrient deficiencies. One to two bananas per day is considered a moderate intake for most healthy people.
How radioactive is Chernobyl?
The ionizing radiation levels in the worst-hit areas of the reactor building have been estimated to be 5.6 roentgens per second (R/s), equivalent to more than 20,000 roentgens per hour. Most, including Akimov, died from radiation exposure within three weeks.
Is Chernobyl reactor 4 still burning?
The accident destroyed reactor 4, killing 30 operators and firemen within three months and causing numerous other deaths in weeks and months that followed. By 06:35 on 26 April, all fires at the power plant had been extinguished, apart from the fire inside reactor 4, which continued to burn for many days.
Is Fukushima worse than Chernobyl?
Chernobyl is widely acknowledged to be the worst nuclear accident in history, but a few scientists have argued that the accident at Fukushima was even more destructive. Both events were far worse than the partial meltdown of a nuclear reactor at Three Mile Island near Harrisburg, Pennsylvania.

Did anyone survive Chernobyl?
Survivors of the Chernobyl nuclear disaster have long lived with a lingering fear: Did radiation exposure mutate their sperm and eggs, possibly dooming their children to genetic diseases? Two plant workers died in the explosion and 28 firefighters died from acute radiation poisoning.
Is the Chernobyl reactor still hot?
The NSC was supposed to stabilize the site, which is still highly radioactive and full of fissile material. However, some worrying signals have emerged from the sarcophagus covering the Unit Four reactor, suggesting the remains could still heat up and leak radiation into the environment all over again.
Is anyone still alive from Chernobyl?
They came from all over the former U.S.S.R. , and most were young men at the time. Perhaps 10 percent of them are still alive today. Thirty-one people died as a direct result of the accident, according the official Soviet death toll.
