Radiation seed therapy is a common method for treating some prostate cancers and brain tumors. Iodine-125, which decays by electron capture followed by gamma ray emission with a half-life of 59.4 days, is one isotope used for this treatment. If a tumor were seeded with 1.00 g of iodine-125 (124.90 g/mol) , what would the initial radioactivity level be? Note: 1 Ci = 3.70 1010/s.
A) 17.6 mCi
B) 32.5 mCi
C) 96.7 mCi
D) 1.40 mCi
E) 58.6 mCi
