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. If you begin with 46.2 mg of this isotope, what mass remains after 11.3 days have passed? mg 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 12.7 percent of its original value? days

Iodine-131, a radioactive isotope of iodine, is used medicinally as a radiotracer for the diagnosis and treatment of illnesses associated with the thyroid gland. The half-life of iodine-131 is 7.0 x 105 seconds. If a patient is given 0.45 g of iodine-131, calculate how long it would take (in seconds) for 90.0% of the iodine-131 to decay.

The radioactive isotope thorium 234 has a half-life of approximately 578 hours. (a) If a sample has a mass of 67 milligrams, find an expression for the mass after t hours. Q(t) = 67e^-0.001199t (b) How much will remain after 85 hours? (Round your answer to one decimal place.) 60.5 mg (c) When will the initial mass decay to 13 milligrams? (Round your answer to one decimal place.) hr
