In order to determine the volume of blood in an animal a 1.0 mL of sample of solution of `10^3` dpm of `H^3`, is infected into the animal blood stream. After sufficient time for circulatory equilibrium to be established, 2mL of blood is found to have activity to 10 dpm. Calculate the volume of blood in the animal.

The initial number of radioactive atoms in a radioactive sample is N_0 . If after time t the number of becomes N, then N=N_0e^(-lambdat) , where lambda is known as the decay constant of the element. The time in which the number of radioactive atoms becomes half of its initial number is called the half-life (T) of the element. The time in which the number of atoms falls to 1/e times of its initial number is the mean life (tau) of the element. The product lambdaN is the activity (A) of the radioactive sample when the number of atoms is N. The SI unit of activity is bequerel (Bq)' where 1 Bq = 1 decay. s^(-1) .
