To find the radioactive decay half-life, you can use the formula:

[ t_{1/2} = \frac{{\ln(2)}}{{\lambda}} ]

Where:

- ( t_{1/2} ) is the half-life,
- ( \lambda ) is the decay constant.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
