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
It is probabilistic. So if an atom has a half life of 1 second, this does not mean that in 1 second that atom will now be a half atom. Instead, it means that on average, that atom will decay within its 1s half life 50% of the time.
