Hi fellow zuikoholics.
The issue of radioactive lenses has been discussed in various threads in here. What I wanted your expert view on is whether there actually are any radioactive Zuikos out there. There are some videos online with people measuring radiation but those readings (to my non-expert view) is negligible compared to other lenses with thorium glass (i.e. Takumar 50f/1.4).
Is anyone aware whether Olympus used thorium in their lenses? I can find resources stating lanthanum being used but this is not a radioactive material.

Too many cameras....

This seems to list a good number of lenses, but I'm not familiar enough with Olympus lenses to make much sense of the entries.

The OM Zuiko 55mm f1.2 lens is said to be slightly radioactive, the glass does yellow as it ages but can be cleared with exposure to UV light.
