Even though it poses about the same danger as background radiation, is everyone aware that radioactive thorium is used in the manufacturing process of Coleman Lantern mantles? Yes, Coleman lantern mantles are radioactive. Don't believe me, look it up. From this article: https://pubmed.ncbi.nlm.nih.gov/6706595/
"Gas lantern mantles contain thorium to produce incandescence when lantern fuel is burned on the mantle. Although only thorium is initially present on the mantle, the thorium daughters build up, some over a period of weeks and some over a period of years, and significant quantities of these daughters are present when the mantle is used. Some of these daughters are released when the lantern fuel is burned on the mantle. The amounts of radioactivity released during burning is studied by measuring the gamma radiation emitted by the daughters. Results of this study show that some of the radium (224Ra and 228Ra) and more than half the 212Pb and 212Bi is released during the first hour of a burn. The actual amounts release depend on the age of the mantle."
I have one I scooped out of a river years ago smelt fishing north of Goderich. My guess is some one was after trout and dumped it when they heard us coming. Cleaned it out and bought a new glass and it was good to go. I have used it to track deer as well, and it works great to light up the toboggan hill at night too, plus makes a great hand warmer. Some guys mount them in homemade sleds with a grate at the top for night ice fishing as well.
That's how I found one of mine,too,SCUBA diving south of Peterborough in the Otonabee River on the bottom in the middle of the channel. No doubt,it fell off a boat. I dried it,cleaned it,put a new generator on it (even the glass hadn't broken) oiled the plunger shaft and added a new mantle. I still have it and still use it. Those things are virtually indestructible.
That’s all we ever used at my dads fishing/hunting camp when I was young.
We had 2 going every night. Drank many beer and rye’s by the mantle light.
Camp rules was to go out on the deck to fill them up.
Made me think, not that long ago we also used them at my buddies moose camp in Quebec, some rules about no generators.
