Re: cerium oxalate- what is its radioactive component?



It's thorium....they used to do the monazite extractions here in West Chicago,
and now we're remediating the site.   In the process of cleanup, we've come
across several product containers (I have one in my collection) for Cerox 747,
a glass polishing compound marketed by Lindsay Rare Earths.
