A medical technician is working with the four samples of radionuclides listed in the table below. Initially, each sample contains 21.00 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 1/8 of the initial amount. sample A B C с D symbol 198 79 191 76 201 81 32 15 radionuclide Au Os TI P half-life 3. days 15. days 73.0 hours 14. days initial radioactivity (choose one) ✓ (choose one) (choose one) ✓ (choose one) ✓ time for amount of radionuclide to decrease to 1/8 of initial amount X days days hours days S
