    The jewelry and aerospace industries use brazing alloys containing gold. The dental profession uses gold extensively. Alloys containing 25 to 70 percent gold are used in wire form for orthodontic applica- tions; other alloys (with 60 to 92.5 percent gold) are used in cast form in inlays, crowns, and bridges.

    Monazite is an important ore for thorium, lanthanum, and cerium. It is often found in placer deposits. India, Madagascar, and South Africa have large deposits of monazite sands. The deposits in India are particularly rich in monazite. Monazite is radioactive due to the presence of thorium and

The calculation of Kithil (34) for the quantity of meso- thorium per ton of monazite sand assumes that the gamma -ray activities of mesothorium and radium are inversely proportioned to their half periods.

    Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium.According to proponents, a thorium fuel cycle offers several potential advantages over a uranium fuel cycle—including much greater abundance of thorium on Earth, superior physical and nuclear fuel properties, and reduced nuclear waste production.
