I have a strong feeling that I will not be alone with this choice - but no matter: This is my version. According to Wikipedia:
An X-ray (or Röntgen ray) is a form of electromagnetic radiation with a wavelength in the range of 10 to 0.01 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (30×1015Hz to 30×1018Hz). They are longer than Gamma rays but shorter than UV rays. X-rays are primarily used for diagnostic radiography and crystallography. X-rays are a form of ionizing radiation and as such can be dangerous. In many languages it is called Röntgen radiation after one of the first investigators of the X-rays, Wilhelm Conrad Röntgen.Thus, in Norway X-rays are always called røntgenstråler and the pictures røntgenbilder. Ususally all this is shortened to rtg. Most people come into contact with X-ray when they are checked for broken bones or other medical defects, or when they are doing their dental check-ups. It is not as easy as one should imagine to diagnose correctly X-ray pictures, and as with all kinds of photography, many demands must be met to achieve the best possible result.I will show you an example of what a typical dental X-ray picture of a grown-up person looks like. The picture was taken in the mid 90s, so hopefully the situation for the same age group is better today.
