X-rays are very short wavelengths of electromagnetic radiation that can penetrate matter to produce an image of bones and internal organs. X-ray images are tools used by physicians and practitioners to confirm a diagnosis or a clinical finding such as extremity fracture or pneumonia.

Most x-ray examinations consist of at least two views of a body part at right angles to one another. X-ray dye or contrast mediums are used in some examinations to make certain structures, such as the kidneys or bowel, appear visible on an x-ray image

Chest x-rays can be self referred for those travelling abroad to work and require an X-ray for entry into the country.
