Concrete is radioactive, granite is radioactive, all kinds of everyday things give off gamma radiation. Worry worry worry.

Ha! Somebody just wants our bitchin' old lenses for themselves. I'll not be fooled!



Scary stuff. For anyone visiting Las Vegas there is something other than gambling there. Something actually cool. A genuine Smithsonian quality ("in association with") museum:

The National Atomic Testing Museum and the NTSHF - Las Vegas, NV

One of the things you'll pick up during your tour is how cool and safe the general public was indoctrinated to believe all that "atomic age" stuff was. Clearly, the legacy endures.

It's really terrifying. After only 42 years of close contact with lenses, my skin is wrinkling. Not only that, but my hair has turned grey and is falling out. Gotta call a lawyer.

Loads of russian lenses reportedly have radioactive properties. That said, I'm quite confident that it's not a real hazard.(Albeit, I'd avoid bringing 30 of these lenses in a bag together through any sort of security checkpoint)

Only one that I've ever heard of, the Industar 61.

Most of the Industar lenses have been accused of such at one point or another. It's on the impurity level(If at all), though. Not like Asahi Pentax's Thorium elements.

This topic pops up every few years. And soon as everyone forgets about it, some n00b will find out about it and broadcast to the world as if they discovered something astonishing. *yawn*

You bet me to it.

I am prepared to help you dispose of any (functional) lenses with radioactive coatings and I will even pay for shipping! Can't get fairer than that.

The dirt in my crawl space is radioactive as is the water in my pipes.

Unless you sleep with your lenses stuffed into your pajamas, I wouldn't worry about. The entire universe, after all, is radioactive.
