A medical technician is working with the four samples of radionuclides listed in the table below. Initially, each sample contains 3.00 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 1/8 of the initial amount. 20 time for amount of radionuclide initial radionuclide to decrease to 1/8 of initial amount sample radioactivity symbol half-life 59 days V (choose me) 1 (highest Fe 45.0 days 26 2. 178 Ta I minutes 9.0 minutes 4 (lowest) B 73 139 Ce I days 138. days (choose one) 58 60 I years Co 5.0 years (choose one) 27
