Would you buy one or is anyone still using any older lenses that have Thorium Oxide as a component of the glass.
It seems there are several good quality lenses from the past that fall into this category but would you risk it?
The amount of radioactivity given off seems minimal compared to acceptable exposure levels in other situations but the thought of it would stop me from owning one.
