Bananas do have radiation, and they are discolored ionizing radiation. But there is no need to panic at all, because all talk of radiation hazards out of dose is unscientific. The radiation of bananas is derived from the radioactive element potassium-40. Because the potassium content in bananas is relatively rich in fruits, the potassium-40 content is relatively higher. How much radiation does bananas have? Direct answer: the amount of potassium-40 in bananas is like dust compared to the amount of radiation that can cause cancer. People usually use the term "banana equivalent dose" to describe the amount of radiation, that is, the equivalent of "how many bananas were eaten" to measure the amount of radiation received. We usually eat a banana, and the additional ionizing radiation dose is about 0.0778 microsievert (the unit of calculation of the radioactive dose), which can be known by the following comparison: The chest CT scan is the equivalent dose of 70,000 bananas; the maximum allowable radiation exposure of the nuclear power plant to the surrounding environment is the equivalent dose of 2,500 bananas per year, and the lethal dose is the equivalent dose of 35 million bananas, which means that 35 million bananas need to be eaten. And our metabolism will control the potassium content in the body, even if we eat bananas, excess potassium will be excreted from the body, so bananas can be eaten with confidence. (CCTV Life Circle)
