A medical technician is working with the four samples of radionuclides listed in the table below. Initially, each sample contains 25.00 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 1/32 of the initial amount. sample A B C symbol 170 69 145 62 241 95 51 radionuclide 25 Tm Sm Am Mn half-life 129. days 340.0 days 432.0 years 46.0 minutes initial radioactivity (choose one) ✓ (choose one) ✓ (choose one) ✓ (choose one) time for amount of radionuclide to decrease to 1/32 of initial amount days days years minutes
