The invention concerns a method and apparatus for scanning bodies, typically human bodies (12) for security or medical purposes. In the method, the body (12) is scanned with a beam (20) of X-radiation of sufficiently low intensity that no physiological damage is suffered. The X-radiation transmitted by the body (12) is then converted into an optical image. The optical image is intensified and converted into an electronic image. The electronic image is manipulated to produce a scanned image of the body or a portion of the body. The scanned image is typically a video image.
