If an Element
is irradiated by X-Rays
it is possible to transfer their energy to the orbital Electron
. The electrons move up an 'energy level' in the process. As these energised electrons fall back to their normal state, energy is released in the form of characteristic discrete x-ray Photons
which are unique to the element in question. The process is used in analytical techniques where element identification is required.
X-rays are part of the Electromagnetic spectrum
. They are a penetrating form of electromagnetic radiation and consist of quantum's of energy (Photon
). X-rays are commonly produced by the excitation of atomic Electrons
, by firing electrons between a high potential difference towards a target (which is the principle of an x-ray machine). The target electrons are excited, and as they de-excite x-ray photons are produced. X-rays can also be produced as a result of Bremsstrahlung
or by nuclear reactions. X-rays have many uses including medical imagining and industrial quality assurance.
Processed crude Uranium
oxide. This is the form in which most uranium is shipped around the world before processing into metallic metal and other forms.
