X-ray developments (1 ene 1920 año – 9 jun 1940 año)

Descripción:

Most of the early X-ray work was performed by doctors and the departments were often combined with electro-therapeutic departments. However, from about 1903 lay X-ray operators were appointed as assistants. Gradually more and more lay X-ray operators were appointed, training courses were set up and the Society of Radiographers was formed.
