Do you care to share the address of your expert so that we can send our lenses to him/her for testing?

That is easy. Don't be in contact for a long time.

Did anyone notice that this is a ZOMBIE THREAD and that all of these things were discussed ad nauseum two years ago?

The thorium is not a coating, but is actually part of the formula for the glass.

Yes, radioactive.



A strip of x-ray film



Film, of course! Unless the camera is a shelf queen. And what protects the film? A couple pieces of glass and a fabric or metal shutter. Thanks for reminding everyone. The lens elements are radioactive and may even set off detectors at airports and elsewhere, but the health risks are very low due to the low energy of the radiation and the poor penetration.

Or the spiders around here either, to be honest! I have a good-sized divot in the middle of my forehead from a spider bite that left a necrotic lesion!

...put spider in jar with lens. Wait one month. Release spider to your hand where he will automatically bite you out of spite. Next thing you know you will be climbing walls!
