Gas Lantern Mantles. W hile it is less common than itonce was, some brands of gas lantern mantlesincorporate thorium-232. In fact it is the heating of thethorium by the burning gas that is responsible for theemission of light. Such mantles are sufficientlyradioactive that they are often used as a check sourcefor radiation detectors.Antique Radioactive Curative Claims. In the past,primarily 1920 through 1950, a wide range of radioactiveproducts were sold as cure-alls, for example, radiumcontainingpills, pads, solutions, and devices designedto add radon to drinking water. The states generallyhave regulatory authority over these devices. In somecases, a state might even require that these devices beregistered or licensed. Most such devices are relativelyharmless but occasionally one can be encountered thatcontains potentially hazardous levels of radium. If thereis any question about the safety of such devices, thepublic is strongly encouraged to contact the stateradiation-control program for advice.For further information contact the following:National Council on Radiation Protection andMeasurements, “Radiation Exposure of the U.S.Population from Consumer Products and MiscellaneousSources,” NCRP Report No. 95, Bethesda, MD, 1987.U.S. Nuclear Regulatory Commission, “Systematic27Gas Lantern Mantles.
