A radioactive waste contains 2 curies (Ci) of 60Co per liter and 2 mCi of 45Ca per liter. The waste can be discharged only if its total activity does not exceed 20 μCi/L. If the half-life of 60Co is 10.7 min and that of 45Ca is 152 days, determine how long the waste must be stored before it can be discharged

Question
A radioactive waste contains 2 curies (Ci) of 60Co per liter and 2 mCi of 45Ca per liter.
The waste can be discharged only if its total activity does not exceed 20 μCi/L. If the
half-life of 60Co is 10.7 min and that of 45Ca is 152 days, determine how long the
waste must be stored before it can be discharged.
