Iodine- 125 (^125 I) is used to treat, among other things, brain tumors and prostate cancer. It decays by gamma decay with a half-life of 54.90 days. Patients who fly soon after receiving ^125 I implants are given medical statements from the hospital verifying such treatment because their radiation could set off radiation detectors at airports. If the initial decay rate (or activity) was 527 mu Ci, what will the rate be after 361.0 days? Number ________ mu Ci How many months after the treatment will the decay rate be reduced to 16.5% of the original value? Number ______ months
