[en] Methods currently being used or developed for the elemental analysis of materials are chemical analysis, non-destructive inspection and calorimetry. The chemical analysis, which removes high-level radioactive elements through chemical treatments and then performs the quantitative analysis using the ICP-MS(Inductively Coupled Plasma - Mass Spectrometer) or the ID-MS(Isotope Dilution Mass Spectrometer), is recognized the most accurate. However, it requires a long, complex pre-treatment process in which a mass spectrometer could be contaminated. To solve this problem, a new method, which can be performed with high-level radioactivity and at high temperature, was desired. Such a method should also have the same accuracy as the chemical analysis, with a less possibility for instruments to be contaminated. In addition, as interests in the environment and the life quality are increased, a detailed analysis on the environmental impacts is also required. Satisfying all of the above-mentioned, Laser Induced Breakdown Spectroscopy (LIBS) technique is being developed. LIBS works by firing laser light at a surface of a sample. The laser beam vaporizes a spot on the target sample and plasma is formed. Light emitted by the plasma, since a spectral lines characteristic of the elements present in the sample make it possible to deduce the elemental composition of the material under study. Many attributes of the LIBS technique make it ideal for industrial applications. For example, it allows on-line or in-situ analysis, which would permit real-time control of these processes. LIBS is a promising technique for the elemental analysis of materials that may be too hazardous. Other main attributes of this technique include no need for sample preparation and its instruments being field-portable. This paper describes the current status on the development of the LIBS technique which uses a laser to analyze solids without sample preparation
