Half life

Half life | Radioactivity | Physics | FuseSchool

This atom has an unstable nucleus. Any moment now it may undergo radioactive decay. Any time now... Or it may not! We just don’t know, as decay is a random event. We cannot predict when any single nucleus will decay. But we can say, if we have a large enough number of atoms, then decay will happen somewhere in a sample. If we time how long it takes for half of the atoms to undergo decay we have a measure, half-life, of a rate of decay.
