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 1/8 of the initial amount. sample A B C D symbol 55 26 227 89 201 81 96 radionuclide 43 Fe Ac ΤΙ Tc half-life 3. years. 22. years 73.0 hours 4.0 days initial radioactivity (choose one) (choose one) (choose one) ✓ (choose one) 1 (highest) 2 3 4 (lowest) time for amount of radionuclide to decrease to 1/8 of initial amount X years years hours days $
