Exam 10: Radioactivity and Nuclear Processes

You inject a 160 lb male patient with 1.0 ml of a saline solution containing a radioactive form of sodium.It has an activity of 5.0 * 10⁴ dpm.After allowing sufficient time for the solution to mix,you remove a 1.0 ml sample of blood and measure its radioactivity.You discover it to have an activity of 11 dpm.What is the patient's blood volume? (Hint: this is similar to a M₁V₁ = M₂V₂ type problem. )
