What does ‘half life’ actually mean? If the radiation level is always half, then would an atom always be radioactive? Could a plutonium atom decay into another non-radiactive element?
Edit: spelling
In: Physics
If you have an atom that has a 1 second half-life. There is a 50% chance that atom will decay in 1 second.
Basically, half-life is the amount of time you have to wait for there to be a 50% chance of an atom decaying.
