Half life is the time taken for approximately half of the available nuclei in a sample of radioactive material to decay into something else it's a characteristic of the isotope, for example, the half life of the isotope of iodine, i131 is 808 days half lives can vary from fractions of a second to. Half-life is defined as the time required for half of any given amount of a radioactive substance (parent atoms) to decay into another substance (daughter atoms) radioactive decay is a constant process where the unstable radioactive element breaks down to become a more stable element by releasing radioactive particles and radiation.
