Haven't seen one of those in half a century. My dad was a photographer, among other things, and we used it to remove dust from 35MM B&W negatives before enlarging and producing 8X10 prints.
I used them as well for dusting off negatives. Probably still have one or two buried in a drawer full of photography paraphenalia.
'for dusting off negatives'
but no banding effects from interacting with the film's actinic radiation?
I would have thought any such exposure should be avoided
I remember comments or warnings against exposure to old wristwatch radium dials ... maybe that was an old urban legend though
I used to use one of these same brushes in the dark room when I was in grad school...enlarging electron microscopy images. Nice stroll down memory lane.
Po 210 is a pretty weak alpha emitter. Won't penetrate skin so it's not much of a radiation hazard. With a 136 year half life, it will be useable for many lifetimes.
It is an alpha emitter so there is no risk if you don't eat it
I believe it's 138 days ... maybe that's what he meant & still wouldn't carry one around in my watch pocket
My bad....misread the unit value.
hope your Dad didn't carry it around in his watch pocket for the first 14 months after he bought it
I remember those making a stir in, I think it was, Mechanics Illustrated
I miss seeing those in the various waiting rooms like 'back in the day'
