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. time for anmount of radionuclide to decrease to 1/8 of initial amount radionuclide initial radioactivity sample half-life symbol 62 Cu minutes 5.0 minutes (choose one A 29 46 Sc 21 days 84.0 days (choose one B 152 Eu 63 years 13. years (choose one) C 201 TI hours 73.0 hours (choose one) D 81 (choose one) 1 (highest) 2 3 4 (lowest) Check Explanation O2019 McGraw-Hill Education.
