  1. Strictly speaking, a half-life is a number with dimensions of time, not an equation. It's value depends upon what the material is.

    If you meant to ask what is the amount N of material remaining After time t, in terms of half life T, then
    N(t)/No = (1/2)^(t/T)
    T is the half life in this equaton, and No is the amount of the radioactive material at time 0.
