The half-life of a substance is the amount of time it takes for half of that substance to decay. However, after two half-lives, half of the half remaining will decay, leaving you with one quarter of the original substance.
So, after 1 million years you will have 50% of the original substance remaining.
And, after 2 million years you will have 25% of the original substance remaining.
