Iodine‑125 (I125I125) 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.54.90 days. Patients who fly soon after receiving I125I125 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 522 μCi,522 μCi, what will the rate be after 377.0 days?
