How long does radiactive material remain radioactive.?
I ask this in light of the issue of Earth's core heating.
It seems to me the radioactivity model has to explain how such material remains seemingly radioactive to this day. 4.5 billion years after the Earth was formed.
Does that defy what we know of material such a uranium etc all of which lose radiactivity over a relatively short period of time compared to the Earth's entire geological history. ?
Or am I mistaken in my understanding of these things ?
