A medical technician is working with the four samples of radionuclides listed in the table below. Initially, each sample contains 9.00 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 1/4 of the initial amount. radionuclide time for amount of initial sample radionuclide to decrease to radioactivity symbol half-life 1/4 of initial amount 67 Ga O hours 78.0 hours (choose one) A 31 131 8.0 days (choose one) O days 53 188 69.0 days (choose one) O days 74 149 Tb D 4. hours (choose one) hours 65 ?
