A medical technician is working with the four samples of radionuclides listed in the table below. Initially, each sample contains 22.00 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 1/32 of the initial amount. radionuclide initial radioactivity time for amount of radionuclide to decrease to 1/32 of initial amount sample symbol half-life 203 Pb 82 2.0 days v (choose one) I days A 1 (highest) 223 2 в Ra 11. days 3 days 88 4 (lowest) 131 Cs 10. days (choose one) | days 55 141 Ce 33.0 days (choose one) I days 58
