Technetium-99m is used to form pictures of internal organs in the body and is often used to assess heart damage. The m for this nuclide indicated an excited nuclear state that decays to the ground state by gamma emission. The rate constant for decay of 99m/43 Tc is known to be 1.16 x 10-1/h. What is the half-life of this nuclide?
