I'm not concerned over the radiation issue of these lenses. I have about a dozen radioactive lenses.
Yes, these thoriated lenses do emit alpha, beta and gamma. Alpha is no concern as it's blocked by the camera itself, or a lens cap.
Use some due diligence in storing them. I keep mine in the garage or in an aluminum case in the dining room.
I simply shoot as usual with them.

We get a greater dosage from other source in our lives than these lenses. The exposure from a number of transcontinental flights annually far exceeds what I will get from taking a few shots with these lenses.


If I ever get a glowing green nose I will send you for free.
