half-life of 4.5 billion years.

Meaning that greater than 99% of its radioactive potential has already expired, and for the ~1% that could split, any given atom has a 50% chance of splitting sometime in the next 4.5 billion years (or another way to think of this is that 50% of the ~1% left will split sometime in the next 4.5 billion years. In other words, a whole lotta nothin' has happened in the last ten years. Or another way of saying this is that it not siginficantly more radioactive than the dirt in your front lawn.
