> I noticed this 24mm f2.0, item #3850125401, and the seller describes:

> "However, the lens has developed a yellowish cast to it due a thorium
> glass
> element. (Reads about 100 counts per minute on my geiger counter. Not
> dangerous, but interesting.) Serial number 100794."

> I didn't know that the 24mm f2.0 had some of the radioactive elements. New
> data to me, and important since this is one that I [eventually] want to
> add to
> my collection. Anybody else have experience like this? The serial number

> very early, so maybe Zuiko moved away from this at some point?
