Problem
ProblemA solution of iodine-131, a radioisotope used in the diagnosis and treatment of thyroid disease, is found just prior to administration to have an activity of 1.08 x 106 Bq/mL. If 2.57 mL were delivered intravenously to the patient, what dose of I-131 ( in µCi) did the patient receive?
A
7.50×10–5 µCi
B
75.0 µCi
C
29.2 µCi
D
0.075 µCi
E
0.029 µCi
