A medical technician is working with the four samples of radionuclides listed in the table below. Initially, each sample contains 20.00 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. radionuclide time for amount of radionuclide to decrease to 1/8 of initial amount initial radioactivity sample symbol half-life 62 Cu 29 5.0 minutes (choose one) A minutes 46 Sc 21 84.0 days days B (choose one) 152 Eu 63 13. years (choose one) years 201 T1 81 73.0 hours (choose one) hours D (choose one) ? 1 (highest) 2 3 4 (lowest) Check Explanation Privacy O2019 McGraw-Hill Education.
