Also, are Coleman lantern mantles radioactive?
The Coleman Company, one of the world's largest makers of camping supplies, continued to use Thorium to make their mantles until the mid-1990s when they changed to yttrium, a non-radioactive compound that does not burn as bright, but burns longer.
Similarly, do Coleman mantles contain thorium? Sometime around 1990, the Coleman Company replaced the thorium in their mantles with yttrium. The yttrium mantle produces about 20% less light, but it lasts longer. According to NUREG-1717, about half of the 50 million mantles sold in the U.S. in 2000 (or thereabouts), contained thorium.
Considering this, what are mantles made of?
The mantle is a mesh bag of fabric impregnated with a solution of nitrates of cerium and one or more of the following metals: thorium, beryllium, aluminum, or magnesium.
Are thorium mantles dangerous?
One potential cause for concern is that particles from thorium gas mantles "fall out" over time and get into the air, where they may be ingested in food or drink. These particles may also be inhaled and remain in the lungs or liver, causing long-term exposure exceeding the risk of background radiation.
Related Question AnswersHow do Coleman mantles work?
They burn a fuel like propane, white gas or kerosene to produce heat, and the heat causes the mantles to produce light. The mantles are a ceramic mesh that encase the flame produced by the lantern. Typical mantles look like this: Mantles start out as silk fabric sacks impregnated with different oxides.Does Coleman fuel go bad?

Can I use my Coleman® stove or lantern indoors? All fuel appliances (Stoves and Lanterns) should be used outdoors in well-ventilated areas clear of combustible materials due to the danger of fire and the emission of carbon monoxide (CO) from burning fuel and the effects of carbon monoxide exposure.Are gas lights dangerous?
In addition, gas lights expel carbon monoxide (CPO) that can be deadly when absorbed into the blood. The fumes a lantern can produce are the same fumes that a running car would give off in a closed garage. CPO is both odorless and colorless, which means that it can potentially kill you without your realizing danger.What type of radiation does thorium emit?
The number of particles emitted is related to the radioactive half-life of the isotope, which is about 14 billion years for natural thorium (thorium-232). The other type of radiation hazard is from gamma rays, which can penetrate the body and pass through the air.How long do gas lanterns last?
