Half-life of the tantalum-172 has to be calculated if after 2 hours the radioactivity is 1 / 16 of initial radioactivity. Concept Introduction: For a radioactive isotope, the relative instability is expressed in terms of half-life. Half-life is the time required for half of the given quantity of the radioisotope to undergo radioactive decay. Half-life of the radioactive isotope is independent of the quantity of the radioactive isotope. Half-life of a radioactive isotope can be expressed as, t 1 / 2 = 0 .693 k
