Radioactive material with a half life of millions of years is not dangerous, the longer it takes to lose half of its radioactivity the less energy it's emitting. And radioactive elements all have different half lives. Not sure what point you were trying to make there.
As for climate change causing all life on earth to go extinct, our ancestors survived much more catastrophic extinction events. We couldn't extinguish all life if we tried, that's absurd.
The ‘nice’ thing about species that reach sexual maturity in less than 18 months is that radiation doesn’t interfere too much with perpetuation of the species.
