The only gas in the series is 220Rn, but its half life is measured in seconds, which means even in a confined space it won't live long enough to reach your lungs. Alpha and beta normally doesn't get trough the lamp glass. This means that thorium ore (might be millions of years old) is more active than the pure metal or purified thorium oxide. Daughter elements though are far quicker and combined emit alpha, beta and gamma. My line of thinking: 232Th has a very long half life, it means a very small amount decays. I have some chemistry background and don't tend to panic just by seeing a radio label, but made me thinking, as it is significantly more contact than "a few hours camping use a year". I am abut to install two Tilley's in our house, expectedly running several hours every day with little ventilation (also want to preserve heat due to current energy prices). ![]() I don't think I'll ever handle a mantle without gloves again! Is there an inhaled level that is still considered harmless (something akin to everyday background radiation or trace amounts) or is that wishful thinking?.Do the mantles give off the same amount of radioactivity all the time, or does it decrease over time? i.e., mostly when mantle is primed?.How much radiation maybe in one ingested particle? Various sources indicate that even the Gold Tops are harmless so long as nothing (smoke or particle) is ingested. /rebates/&.com252flighting252flighting-accessories252fstring-tie-11-mantles252fSP270762.Is it mantles made in specific countries that are nowadays radioactive vs.Do the current green top Coleman mantles that are readily available (Amazon, Canadian Tire, etc.) contain thorium or any other radioactive element? Some Q&As on Amazon say yes, but they're not verifiable sources.How much thorium did the Coleman Gold Top mantles 21A101C contain?.And, quite frankly, that now terrifies me. While I didn't sit in the smoke, I guess it's not out of the question that I may have inhaled a puff of smoke or even a tiny piece of ash that may have gone flying. The first one that I primed on the lantern I did really slowly (maybe 2-3 minutes to ash) and it gave off a fair bit of smoke. Due to the lantern being on the newer end, I assumed (wrongly?) that the mantles would not be radioactive. It is manufactured in April 2002 and came with a package of two Coleman Gold Top mantles. ![]() ![]() To give you some background info, I got a Coleman 286A this week. not in specific mantles, but the ones I am looking into are not included. A thread ( Radiation Levels in Some Old and Newer Mantles) makes reference to radioactivity vs. I've been searching for a couple of days regarding radioactivity (as well as levels and potential ill effects) of the Coleman Gold Top and current green top mantles.
