The Blood Volume of a Patient Can Be Measured by Using

True/False

The blood volume of a patient can be measured by using chromium-51, a positron emitter, administered as a solution of sodium chromate. The nuclear equation for the decay of chromium-51 is: ${ }_{24}^{51} \mathrm{Cr} \rightarrow{ }_{23}^{51} \mathrm{~V}+{ }_{+1}^{0} \mathrm{e}$
