A medical technician is working with the four samples of radionuclides listed in the table below. Initially, each sample contains 15.00 umol 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 1/32 of the initial amount. radionuclide time for amount of initial radioactivity sample radionuclide to decrease to symbol half-life 1/32 of initial amount 85 65.0 days (choose one) v O days A Sr 38 212 B Pb 11. hours (choose one) v |hours 82 91 59.0 days (choose one) O days Y 39 95 Zr 64.0 days (choose one) v I days D 40
