the time it takes for the level of radioactivity to increase by one half
the time it takes for the mass of the element to decrease by one half
the time it takes for half the protons to convert to neutrons
the time it takes for half of the atoms to decay
the time it takes for half of the alpha rays to be emitted
the time it takes for the level of radioactivity to increase by one half
