C) suppose a patient is given 15.0 ug of Th-229 for cancer treatment. what is the activity of this Th-229 in Ci?

D) if the patient in part C) weighs 65kg what does of radiation do they receive (in rem) from the Th-229 over the course of one day? assume that each decay event produces 8.01x10^-13J of energy and that the R.B.E is 20
