Radioactive coating

Any info about Thorium & Lanthanum used in the coating of the lens elements?109.167.192.232 (talk) 17:17, 27 June 2012 (UTC)[reply]

I don't believe radioactive elements were using in the coating, but were actually part of the glass. http://www.orau.org/ptp/collection/consumer%20products/cameralens.htm Icd (talk) 07:03, 28 June 2012 (UTC)[reply]
