MESTECC's YEO Bin should read this (translated from German):

Today we are talking about radiation, radioactivity in everyday life. Radioactivity is everywhere around us, and it is vital for all of us, because without the decay heat of radioisotopes the earth would have solidified completely long ago.We are less aware of this in everyday life, but we encounter radioactivity in a different form. For example in the form of a banana. Bananas are the most radioactive fruit - they contain a lot of potassium, and about one thousandth of the potassium in the environment is radioactive. A wagonload of bananas is so radioactive that it even triggers detectors designed to prevent nuclear smuggling at US ports. One banana emits about 15 becquerels. For this reason, the banana is even used as a unit of measurement for radiation effects on the human body. A so-called banana equivalent dose corresponds to about 0.1 microsieverts. This is the radiation you get when you eat a banana.Other radioactive sources in everyday life are comparable. For example, a study by the International Atomic Energy Agency shows that walking on cobblestones for an hour corresponds to the intake of two bananas. Most cobblestones consist of granite. Granite contains many radioactive elements. If, instead, you stand on a parking lot covered with slag from a coal-fired power plant, this corresponds to about four bananas. A transatlantic flight is, depending on the conditions, about one hundred to one thousand bananas. One chest X-ray yields 200 banana equivalent doses. If, on the other hand, you stand about three-quarters of a meter next to a Castor container, the radiation exposure already corresponds to about a thousand bananas.The most important source of natural radioactivity, however, is radon. This is produced as a decay product in radioactive rocks such as granite and accounts for more than half of the natural radiation dose - on average 11,000 bananas per year in Germany. Those who live in the low mountain ranges may receive the same dose as direct radiation from the rock.This is only surpassed by medical radiation doses: one computer tomogram of the entire body corresponds to over eighty thousand bananas - that is twice the average radiation exposure per year. Sounds like a whole lot - but the lowest radiation dose for which an increased cancer risk is directly proven is 100 millisieverts. One million banana equivalents. This means that you can not only continue to eat bananas with complete peace of mind, but you can also move around in everyday radioactive life without any worries. The only thing you should not do is lick uranium ore.Translated with www.DeepL.com/Translator
