Iodine-131 is used in medical images for CT scans with contrast. Iodine-131 decay is first order with a half-life of 8.0 days. If a patient is administered a typical dose of 370 mg Iodine, how much Iodine-131 will remain after 24.0 days?
1. 1. Iodine-131 is a radioactive isotope. After 8.00 days, 50.2% of a sample of 131I remains. What is the half-life of 131I? 2. The half-lives of different radioisotopes are given in the table below. If the initial amount of potassium-44 is 9.2 g, how much potassium-44 is left in the body after 44 minutes? 2. 32P is a radioactive isotope with a half-life of 14.3 days. If you currently have 59.9 g of 32P, how much 32P was present...
Iodine-131 is administered orally in the form of NaI(aq) as a treatment for thyroid cancer. The half-life of iodine-131 is 8.04 days. How much time is required for the activity of a sample of iodine-131 to fall to 17.5 percent of its original value? ____days Nitrogen-13 is used in tracers injected into the bloodstream for positron emission tomography (PET). The half-life of nitrogen-13 is 10.0 minutes. If you begin with 45.1 mg of this isotope, what mass remains after 27.2...
lodine 131 has a half life of 8 days and decays by a first order process (as is always the case for radioactive decay). How much of a 46 gram sample of iodine 131 will remain after 8 days? Report your answer in grams.
