Cerium oxide is usually contaminated with minute amounts of thorium =
oxide. Though cerium isn't the problem, it's found in the same minerals =
as the thorium. Removing the last traces is nearly impossible.

Thorium IS a radioactive element, it emits alpha particles.=20

Use good housekeeping when working the cerium oxide so it isn't inhaled =
or ingested. That's where alpha particles do their harm.
