this lovely ancient super 8 camera contains a lens that was made partly out of the radioactive element thorium.
by adding thorium to the lens glass, a high refractive index could be achieved while maintaining a low dispersion. thus, radioactive camera lenses used to be state-of-the-art in high-demand photography.

i scored this lovely old camera at a flea market. the lens partly consists of the radioactive element thorium.
by adding thorium to the lens glass, a high refractive index could be achieved while maintaining a low dispersion. thus, radioactive camera lenses used to be state-of-the-art in high-demand photography.
oh, and here’s a better picture:
