A banana contains naturally occurring radioactive material in the form of potassium-40.. Banana equivalent dose (BED) is an informal unit of measurement of ionizing radiation exposure, intended as a general educational example to compare a dose of radioactivity to the dose one is exposed to by eating one average-sized banana.
The banana equivalent dose is sometimes used in science communication to visualize different levels of ionizing radiation. The collective radiation background dose for natural sources in Europe is about 500,000 man-Sieverts per year. The total dose from Chernobyl is estimated at 80,000 man-sieverts, or roughly 1/6 as much. [1]
The banana equivalent dose, defined as the additional dose a person will absorb from eating one banana, expresses the severity of exposure to radiation, such as resulting from nuclear weapons or medical procedures, in terms that would make sense to most people.
RSV vaccine side effects in older adults . The CDC lists the following as possible side effects of the RSV vaccine: Pain, redness, and swelling where the shot is given. Fatigue. Fever. Headache ...
The equivalent dose is calculated by multiplying the absorbed energy, averaged by mass over an organ or tissue of interest, by a radiation weighting factor appropriate to the type and energy of radiation. To obtain the equivalent dose for a mix of radiation types and energies, a sum is taken over all types of radiation energy dose. [1]
Equivalent dose (symbol H) is a dose quantity representing the stochastic health effects of low levels of ionizing radiation on the human body which represents the probability of radiation-induced cancer and genetic damage.
The banana equivalent dose is the dose of ionizing radiation to which a person is exposed by eating one banana. Bananas contain potassium . Natural potassium consists of 0.0117% of the radioactive isotope 40 K (potassium-40) and has a specific activity of 30,346 becquerels per kilogram, or about 30 becquerels per gram.
This is wrong - Sv is an unit of the equivalent dose, so the same number of sieverts should cause similarly severe health effects. The real issue here is that the conversion from Sv to Bq is very complicated and needs to take into account many factors, including the age of the exposed person, route of exposure, and others.
