3.(20 Points) The oral administration of radioactive 131I is a standard treatment for thyroid carcinoma. One consideration for this therapy is assuring that other people do not receive significant radiation exposure. A recent study of 250 patients determined that the average half-life is 14 hours when orally administered to humans.

a)Determine the rate constant (k) for the removal of 131I.

b)According to federal regulations, individuals receiving 131I treatments must be confined as in-patients until their burdens of radioactivity fall to âsafeâ levels. Assume that a patient reaches a âsafeâ level when 95% of the 131I has been eliminated. Calculate the time needed for a patient to reach this level.
