A medical technician is working with the four samples of radionuclides listed in the table below. Initially, each sample contains 18.00 umol 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. radionuclide o. sample initial radioactivity time for amount of radionuclide to decrease to 1/16 of initial amount symbol half-life A 90 Y 39 64.0 hours (choose one) hours 122 1 B 4.0 minutes (choose one) minutes 33 177 C Lu 7.0 days (choose one) I days 71 33 D P 25.0 days (choose one) days 15 5 ?
