nuclear decay (decomposing) rate. half life is the time it takes for an average nuclear particle (of some type that is radioactive) to decay down to its next level.

Half-life isn't necessarily dedicated to the decay of radioactive elements, but can refer to any exponential decay function. Assuming a fuction follows the following equation:
x(t) = A*exp(-b*t)
then the half-life would be the time (t) for the equation to equal A/2, or for exp(-b*t) to equal 0.5.

the time required for half the atoms of a radioactive substance to disintegrate or the length of time it takes for a radioactive substance to lose one-half of its radioactivity. Radioactive isotopes have half-lives ranging from split seconds to thousands of years.
