lodine-123 is a radioactive isotope used in medicine to test the function of the thyroid gland. Its half-life is 13.1 hours. A 475-microcurie (μCi) dose of iodine-123 is administered to a patient. The quantity, Q, left in the body after t hours is given by the equation Q = 475 5(1) 2 13.1 . Answer parts (a) through (d).
