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 1/8 of the initial amount. sample A C D symbol 60 27 103 46 55 26 141 radionuclide 58 Co Pd Fe Ce half-life 5.0 years 17. days 3. years 33. days initial radioactivity (choose one) ✓ (choose one) ♥ (choose one) ✓ (choose one) ✓ time for amount of radionuclide to decrease to 1/8 of initial amount years days years days Ś
