A 1.6-mCi source of 3215P (in NaHPO4), a emitter, is implanted in a tumor where it

Question:

A 1.6-mCi source of 3215P (in NaHPO4), a β emitter, is implanted in a tumor where it is to administer 32 Gy. The half-life of 3215P is 14.3 days, and 1.0 mCi delivers about 10 mGy/min. Approximately how long should the source remain implanted?
