Which Pentax Lenses Are Radioactive. I got a takumar 28mm and 35mm f/3.5 coming in. I did lots of tests with thorium oxide glass in the 1990 decade from pentax, olympus and other and the radioactive level is very low. Here are the latest measuring results of my research into the radioactivity of takumar lenses. Don't have a geiger counter but may get one, due to all the youtube videos. The radioactive components were actually incorporated into a glass (in order to minimize its dispersion) and not used for surface coating (ir coating) of lenses which is. There are a significant number of lenses produced between 1940 and 1970 that are measurably radioactive, like the pentax smc takumar 50mmf/1.4 lens walker shows in the video above. Radioactivity is not limited to.
