For nuclear promoters information. Not only is nuclear power the most carbon producing form of energy it leaves a legacy of killing. Here are the stats; half life does not mean it is safe, it is still a killer; half lives of Plutonium 244, 80 million years, Pl 239, 24,100 years, Pl 238, 87.74 years, Pl 242, 373,300 years, plus Pl 244 and 238 and 239 and 241 are a FISSILE which means they can be fused with other metal and are used in making weapons so once used to kill will just keep killing.
For those who think the wealth they accumulate can out live those half lives, please look at the above numbers. It may be too late for life on earth. SORRY.

P.S.: Natural Plutonium is very rare; most is created by man in nuclear reactors. Two estimates of a pound of Plutonium vapourized and put into the atmosphere can kill (1) 8 billion people or (2) 2 million people.
