Just How Radioactive is Uranium Ore? | TalkNuclear

So, just how radioactive is uranium ore? And, how does it compare to other naturally occurring radioactive substances we are exposed to on a daily basis? Say, bananas for instance. Well, a handful of raw uranium ore actually has about as much radiation as 10 bananas – a "bunch" that is. But, how could that be? It's simple really.
