A medical technician is working with the four samples of radionuclides listed in the table below. Initially, each sample contains 18.00 µumol 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 sample radionuclide to decrease to radioactivity symbol half-life 1/32 of initial amount 145 340.0 days I days A Sm (choose one) O 62 46 84.0 days days В Sc (choose one) O 21 60 C Со 5.0 years (choose one) years 27 18 D F 2.0 hours (choose one) O hours 9
