title: Licencing of medical x-ray equipment in 1899: background and procedure.
abstract: The full text of probably the first worldwide licencing procedure for x-ray equipment has now become available. The document is dated 27 December 1898 and is a formal request from one authority to another to look into what was going on in an institute which called itself Institut für Röntgenuntersuchungen. In response to this, a committee considering both formal and scientific aspects of licencing was founded. This paper shows in brief the scientific background on the detrimental radiation effects available at the turn of the century, and reports on the decisions made by the authorities.
