2013 The Half Life of a Radioisotope By Jeremiah Stoddard Abstract: The half-life of a radioisotope is the time required for half the atoms in a given sample to undergo radioactive‚ or nuclear‚ decay. Half-life is given the symbol t1/2.Different radioisotopes have different half-lives. The amount of radioactive isotope remaining can be calculated using the equation‚ ln [ (A)0 / (A) t1/2 ] = kt1/2 ‚ or‚ rearranged: ln 2 = kt1/2. A sample data set was provided due to safety concerns. Using
