I was testing some of my vintage Rolex dials for radioactivity with a dosimeter.
Out of curiosity, I pulled out some of my rangefinder lenses and tested them. I had one collapsible 50mm Summicron that I was almost positive was radioactive but it was not. So then I tried the 35mm f1.5 Canon and the dosimeter went haywire.
SUPER high radiation.
It's curious, because I never see that lens mentioned as having radioactive elements. I wonder if my is a fluke or maybe it is not just common knowledge.
Can anyone shed any light? A Google search does not reveal much.
