Answer 1. A radioisotope decays from 150 mg to 120.2 mg in 5 days. Calculate the half-life of this isotope. Solution From N t = 1 2 t t 1 / 2 N o we rearrange this equation to take the form t 1 / 2 = t log 2 log N o N t = 5 log 2 log 150 120. 2 = 15.6482 days 2. Iodine-131 has a half-life of 8 days.
