Bananas have gone nuclear!

So it seems that potassium-40 (40K) is naturally occurring in bananas and that it can undergo a disintegration, emitting a positron in the process. This positron can then interact with an electron, emitting 2 photons around 511 keV, in the gamma ray portion of the EM spectrum. This is of course assuming that the pair electron-positron have a low kinetic energy.

As said, bananas have gone nuclear!
