A small quantity of solution containing na24 radio nuclide (half life = 15 hour) of activity 1.0 microcurie is injected into the blood of a person. A sample of the blood of volume 1 cm3 taken. After 5 hour shown an activity of 296 disintegrations per minute. Determine the total volume of the blood i the body of the person. Assume that radioactive solution mixes uniformly in the blood of the person. (1 curie = 3.7 x 1010 disintegrations per second)
