A container used for storing radioactive waste is made with thick concrete and lined with lead on the inside.
Why is lead used to line the inside of the container?
It prevents the radioactive isotopes from decaying further.
It reduces the total weight of the storage container.
It absorbs ionizing radiation to prevent it from escaping into the environment.
It increases the half-life of the radioactive waste.
