The half-life of a radioisotope signifies the time taken for half of the radioactive atoms in a sample to decay. It represents the rate of decay and guides calculations of remaining radioactive material.
Half-life is the time it takes for half of the radioactive atoms in a sample to decay. It is a constant characteristic of a radioisotope and indicates the rate of decay.
One way to determine the amount of radioactive isotope remaining after a given number of half-lives is to use the formula:
(Remaining Amount) = (Initial Amount) x (1/2)^(number of half-lives passed).
