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.
Whilst equivalent dose is used for the stochastic effects of external radiation, a similar approach is used for internal, or committed dose. The ICRP defines an equivalent dose quantity for individual committed dose, which is used to measure the effect of inhaled or ingested radioactive materials.
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.
Unhealthy Ingredients: Sodium nitrite, sodium nitrate, and sodium phosphate. Processed red meat is any type of red meat (think pork, beef, lamb) that has been cured or preserved in any way. This ...
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]
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.
First of all, it’s important to note that the Food and Drug Administration (FDA) does not review or approve dietary supplements for how safe or effective they may be (though brands are ...
It seems that there is a discrepancy of 100 times in the value of the dose received as a result of eating one banana, as quoted in this here article and as quoted in the article on Banana Equivalent Dose (BED). This here article states it is 0.0001 mSv, the article on Banana Equivalent Dose states it is 0.001 μSv.
