“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe
Living at a dark site, I make scope when I have the inclination. I also do woodworking, cycling and other outdoor activities
Quote:JohnH,Tritium is a gas. What you have sounds like Radium paint, which is not to be trifled it. Hopefully you have it stored in a well sealed container. In that state it is safe, but if spilled, a bona fide hazmat situation.

Quote:Older clock and watch dials were hand painted with Radium paint. The brush that the workers used was very fine and to keep the brush tip at a sharp point the workers would wet the bristles with their lips. Guess what happened to most of the workers. Radium was used because it is in nature and lasts a long time. Watch out for old watches.Bill
