You haven't really stated a question. But the half-life of an isotope is the amount of time it takes for half of the sample to undergo radiactive decay, or for half of any sample to undergo any type of decay in general. The half-life is often represented as t_1/2, where 1/2 is a subscript. If you start with a mass m and leave it for a time T, the remaining sample at the end of this time would be equal to m*(1/2)^(T / t_1/2).

No. we could say you have 100g of Thorium-234. After 24.a million days, you have got 50g. After yet another 24.a million days, you have got 25 grams.... The decay is compounding as in it decays 50% from the present volume. even regardless of the undeniable fact that, after a definite volume of the throrium is decayed, the a million/2 existence should not be as precise anymore. a million/2 existence is a statistic. e.g throwing one hundred pennies interior the air-- statistically, 50 would be heads, and 50 would be tails. ok, what happens once you get to a million penny? i'm hoping this helps.
