In addition to artifically induced radiation, some green zircon, as well as other gemstones, are radioactive due to naturally occuring uranium, thorium, or other materials in the stone. However, there has been a significant release of radionuclides in the form of pet waste from cats being treated for cancer with radioisotopes. Metal tables contaminated with cobalt-60 were found scattered across several states. Other offenders include art glass, cloisonne enameled jewelry, and glazed pottery. A more significant concern is the disposal of smoke detectors since the americium eventually accumulates in landfills or wherever discarded smoke detectors wind up. in the mineral.
