Radioactive waste is often mixed with concrete (cementation) before being stored in steel containers.
Why is this solidification process used?
It decreases the half-life of the radioactive waste.
It immobilizes the waste in a solid block, preventing it from leaking or dispersing into the environment.
It reduces the rate of radioactive decay.
The concrete chemically neutralizes the radioactivity of the isotopes.
