A medical technician is working with the four samples of radionuclides listed in the table below. Initially, each sample contains 23.00 µmol of the radionuclide. First, order the samples by decreasing initial radioactivity. Then calculate how long it will take for the amount of radionuclide in each sample to decrease to 1/16 of the initial amount. radionuclide time for amount of initial radioactivity sample radionuclide to decrease to symbol half-life 1/16 of initial amount 149 Tb 4.0 hours (choose one) v |hours 65 137 Cs 55 B 30.0 years (choose one) v years 90 Sr 38 29.0 years (choose one) v O years
