Abstract
The present invention discloses a method for determining an atomic number of a location on a material using a radiation at a predetermined energy. The method comprises the steps of (i) generating the radiation at a first spectrum and a second spectrum penetrating through the location on the material; (ii) detecting a first profile corresponding to the first spectrum and a second profile corresponding to the second spectrum; and (iii) determining the atomic number of the material at the location based on the first profile and the second profile.
