Half-life remaining fraction

Explore statistical radioactive decay over several half-lives.

Start with the idea

This calculator is a scientific workspace. Read the quantities and units first; use the equation only after the physical meaning is clear.

N/N₀ = (1/2)^(t/T½)

Reference constant used by this model where applicable: 0.5. Keep SI units consistent before interpreting a numerical result.

Before trusting the result, ask whether the units and order of magnitude make sense. A calculator cannot rescue a wrong physical model.
