A medical technician is working with the four samples of radionuclides listed in the table below. Initially, each sample contains 10.00 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 1/4 of the initial amount. sample A B C D symbol 52 25 75 35 103 46 188 radionuclide 74 Ma Br Pd W half-life 60 days 98.0 minutes 17. days 69.0 days initial radioactivity (choose one) (choose one) B (choose one) B (choose one) time for amount of radionuclide to decrease to 1/4 of initial amount days minutes days days

For a radioactive sample with a half-life of about 94 days, storage in a lead lined cabinet for a sufficient length of time assures it will be safe before disposal. A radioactive sample is considered to be safe after 10 half-lives have expired. What percentage of the original radioactivity of the sample remains after this many half- lives? Report answer as a percentage, but do not include the percent symbol. Provide 3 significant digits of precision.
