text: It is highly radioactive and has a short half-life, so its natural abundance is very limited and is present in trace amounts.
text: As you point out, polonium (all isotopes of it) has far too short half life for any significant amount to be still around from the formation of the Earth.
text: Polonium needs to be replaced in these devices nearly every year because of its short half-life; it is also highly radioactive and therefore has been mostly replaced by less dangerous beta particle sources.

text: Since radiogenic polonium has a very short half-life (usually measured in fractions of a second), Gentry argues that, if granite takes thousands to millions of years to form as mainstream geology believes, any polonium originally present would have decayed away long before the granite could have formed and could not have produced these haloes.
