Kegunaan isotop iterbium
- 169Yb (with a half-life of 32 days) emits gamma rays and can be used to create a radiographic image of an object without the use of electricity. A capsule containing 169Yb is placed on one side of the object being screened and photographic film is placed on the other. The result will indicate flaws in metal casting or welded joints,. Gamma cameras use 169Yb as a radiation source (Fig. IUPAC.70.1). Gamma cameras are used to locate sealed radioactive sources and hot spots in historical waste. Images of the gamma ray intensity are made and then the 2-D distribution is superimposed on a picture or video image,. 171Yb has been used for making an atomic clock by making use of a ytterbium optical lattice (formed by the interference of counter-propagating laser beams) (Fig. IUPAC.70.2),,.
