If radioactive elements decay over time, and after turning into other radioactive elements one day turn into a stable element (e.g. Uranium -> Radium -> Radon -> Polonium -> Lead): Does this mean one day there will be no radioactive elements left on earth?

Interesting fact, there used to be naturally occurring nuclear reactors. Right now I believe U-235 it about .7% of uranium. But a long time ago before a lot of it decayed away, it was around 3%. And we can see geological evidence of uranium masses underground that had rain water flow through them acting as a moderator.
But theoretically it will all decay away at some point. Not sure if Earth will still be around by then though. I am sure someone on here knows though!
