Oh, and for the scientifically literate:

The decay energy of k-40 is actually more than the decay energy of cs-137 (1.33MeV vs 1.176MeV) and both are beta radiation.

For the non scientifically literate, that means the potassium in your banana is actually slightly more dangerous (more tissue damaging energy released) than the cesium when both have the same activity (bequerels).
