Re: Cerium Compounds

Back when I was doing aerial survey work I did a survey of the RMI facility
up in Ashtabula, Ohio.  Next door to the RMI facility was a facility where
they were processing ilmenite.  The shine from that facility made surveying
the RMI facility very difficult.  If I remember correctly it was mostly due
to thorium in the ilmenite, which was the problem.

        FYI - I was commissioned to do a study at a monazite facility.  The
processing of ilmenite and zircon had virtually no radioactivity.  The
monazite was hot but restricted to a small portion of the plant.
