A medical technician is working with the four samples of radionuclides listed in the table below. Initially, each sample contains 17.00 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 18 9 75 35 177 71 152 63 radionuclide F Br Lu Eu half-life 2. hours 98.0 minutes 7.0 days 13. years initial radioactivity (choose one) (choose one) O (choose one) (choose one) time for amount of radionuclide to decrease to 1/16 of initial amount hours minutes days years
