Radioactive lenses
Mar 31, 2013

I was surprised to read a post about a lens that had radioactive thorium in it.

I looked it up and it seems it was reasonably common in the 60s.

It would be worth noting the model that have it in them as legacy lenses are popular on Nex cameras.

Here is one list I found:
