Bananas have naturally high-levels of potassium and a small fraction of all potassium is radioactive. Each banana can emit . 01 millirem (0.1 microsieverts) of radiation. This is a very small amount of radiation.

Are rad and rem the same?

rem, unit of radiation dosage (such as from X rays) applied to humans. Derived from the phrase Roentgen equivalent man, the rem is now defined as the dosage in rads that will cause the same amount of biological injury as one rad of X rays or gamma rays.
