no exposure to that kind of stuff is smart, and that even goes for this brush , with what used to be considered a benign level of radio activity. Today the understandings are more advanced , and all exposure is best limited, and no longer is any exposure considered benign.

MY brother owned southwestern optics, and used one of those brushes, saying it was the most effective for dust removal when working on glass. The brush was old, but so hot that the box it came in had burned brown under the location of the radioactive strip over the years, , as though it had been exposed to heat.

I warned him not to mess with it, he said it was so low level as to be harmless, disagreeing with my warnings. He died from cancer, probably from breathing in dust from the mildly irradiated carborundum used to work the optical glass at the kit peak optical lab, a national science site that made optics as commissioned by the government.. the radio active treatment of the polishing grit was to make at the abrasive surface harder.

He had a group photo from work, every single optical worker in the photo was either dead from lung or stomach cancer, with two from alcoholism. He was the last guy alive in that picture, probably because he designed and supervised, and only worked on very difficult , or large, fabrications.

Why look for health problems, throw it away. I use a zerostat, a small gun shaped device the generates ions to release static electricity by squeezing a piezo electric element.
