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. sample A B с D symbol 55 26 152 63 88 39 59 radionuclide 26 Fe Eu Y Fe half-life 3.0 years 13. years 107. days 45.0 days time for amount of initial radioactivity radionuclide to decrease to 1/16 of initial amount (choose one) ✓ (choose one) V (choose one) V (choose one) ✓ years years days days
