Nuclear Decay

Radioactive decay is a first-order kinetic process where an unstable atomic nucleus loses energy by radiation. The rate of decay is proportional to the number of radioactive nuclei present. This calculator uses the half-life equation to model this process. Ensure that units for time and half-life are consistent.
