WebbDefinition: Half-Life (𝑡 1/2) Half-life is the amount of time required for one-half of the radioactive nuclei in a sample to decay. Half-life is an intrinsic property. This means that, regardless of the amount of material present, the half-life will be the time required for half of the material to decay.
