    Radioactive lenses - yikes!

    Hello again my APUG friends...

    Dropping in to share a link that might be of interest to the community; came across a blog posting via www.petapixel.com about the radioactivity found in a number of the older lenses still floating about. Hopefully I don't scare anyone with this stuff but it's an interesting view nonetheless:

    It would be interesting to compile a database of these lenses... what do you think?

    All the best,
    Eros

    OK but usually I have a camera body between rear element and my body.

    On the other hand, this is a good caution not to use the lens as a loupe.

    I remember reading about all the radioactive lenses some 30yrs ago. The amounts are very small . We are subjected to much worse on a daily basis anymore.

    They might have a little Thorium, but boy; are they good. I'm referring to the Super-Multi-Coated Takumars.

    these lenses are less than a bunch of bananas...

    I work in a building made of granite--- I can't even measure the radioactivity in a thorium lens because of the very high background coming from the building itself.

    Thank you. The people who built the original sarcophagus over the exploded Chernobyl power plant were in real danger, not the photographers who like to think more about the small amount of radioactivity of their lenses instead of what to put in front of them.
