A small quantity of solution containing Na24 radio nuclide (half-life=15 h) of activity 1.0 microcurie is injected into the blood of a person. A sample of the blood of volume 1cm3 taken after 5h shows an activity of 296 disintegrations per minute. Determine the total volume of the blood in the body of the person. Assume that the radioactive solution mixes uniformly in the blood of person. (1 curie =3.7×10^10 disintegrations per second)
