Gallium: A rare metal with the atomic weight 69. There are several isotopic forms of gallium that differ from it in atomic weight. One is gallium-68, which is produced by cyclotrons and emits gamma rays. The citrate form of gallium-68 is used as a radiotracer to locate sites of inflammation and tumor tissue within the body.
