Cough ..... Cough ....... Bu . . .. . It's been 50 years and not a single soul has ever been harmed. Either someone is pulling yours or you are pulling ours.

But I digress. Feeding time is over.

There's a little American flag on it, I think. It's really old. China probably wasn't even open for trade with the USA when this F2 was made.

Is this why there is a faint green glow coming from my elderly Domke F2 every night?

OK, so cell phone radiation is non-ionizing. I stand corrected.

Someone else used a smoke detector as an example.

Most smoke detectors sold in America contain americium-241, a radioactive element with a half-life of 432 years. You get more ionizing radiation protecting yourself from dying of smoke inhalation in a house fire than you get changing a Super Takumar lens. :cool:

I bet we get more microsieverts (there's a word I didn't know last month) from our cell phones in a day than we'd get over a lifetime from a Tak 50.
