and seemingly innocent ...
The banana is a food radioactive. Yes, yes, but not panic. The radiation dose is less than that received daily by the environment and is light years from which we get if we make an x-ray, for example.
This fruit contains potassium (in fact the third most of Abundant metal of our body), and each metal includes, at a time, all isotopes . This means that there are also potassium-40, which is radioactive. The amount is tiny, but measurable, and be sure, not bad at all.
When a shipment of tons of bananas goes through the control of radioactivity in ports and airports can set off alarms, because the concentration of several thousand units is sufficient to be detected by the security apparatus .
Brazil nuts, on top of radioactivity healthy
Again, it is a negligible quantity which is in the banana ta going to take this afternoon, but there is more radioactive foods: beans, avocados, nuts, and, above all, the nut Brazil, the food with more radiation is known (directly contains radio).
Information for this post we have found in Microsiervos , the best blog in English about science and technology. If you do not know what you're missing the best of the web!
Having said that is solemnly established the banana as the official dessert of this blog.
