X-ray equipment and interfering radiators; application for a permit to operate or notification of operation.

You must usually apply for a permit or report it in order to operate an X-ray facility or an interference source.


As a rule, the operation of an X-ray device or an interference source is either subject to approval or requires notification. This depends on the type of device or its use. The Trade Inspectorate or the State Office for the Environment issues the permit or accepts the notification upon your application.

The operation of X-ray equipment is subject to approval if it does not have a type approval or a CE marking according to the Medical Devices Act (MPG). A permit is also required for X-ray equipment used in technical radiography for coarse structure analysis in materials testing, for X-ray therapy, teleradiology, for early detection of diseases, for operation outside an X-ray room, in an X-ray room for another X-ray equipment (demonstration operation), or for operation in a mobile X-ray room. X-ray equipment that does not fall under this category is subject to notification.

Interference sources that fall under Annex 3, Part D of the Radiation Protection Ordinance (i.e. interference sources for which an accelerator voltage of 30 kV is not exceeded or those with a type approval) do not require a permit, otherwise they require a permit. A notification procedure is not provided for interference sources.

Significant changes in operation must be treated in the same way as commissioning (notification, application for approval).

Detailed information can be obtained from the responsible trade supervisory office.


  • The application or notification must be available.
  • The applicant must be reliable.
  • A radiation protection officer must have been appointed.
  • Sufficient persons with the required expertise in radiation protection or with the required knowledge in radiation protection are available.
  • The equipment and measures for radiation protection must correspond to the state of the art (test report of an expert, type approval if necessary, CE marking according to Regulation (EU) 2017/745 or MPG).
  • The activity must be justified in principle.
  • Other regulations under public law must not conflict with this.
  • For the medical field, there are further requirements such as presentation of the license to practice medicine, display instrument for radiation exposure, consultation of a medical physics expert.


Submit the documents to the trade supervisory office of the administrative district in which you have your business address (residence, if applicable). For the fastest possible processing of your application, it is recommended - if available - to use the corresponding online procedures.

For X-ray hybrid devices, the documents must be sent (in writing) to the State Office for the Environment.


The X-ray equipment may be put into operation no earlier than four weeks after notification to the responsible trade supervisory office. Operation at an earlier point in time is only permissible if the office issues the operating permit as part of a notification confirmation.

In the approval procedure, the X-ray equipment or the interference source may only be put into operation after the approval has been granted.

Required documents

  • Printout of the appointment of radiation protection officers
  • Evidence of professional competence
  • Type approval certificate and/or test report of the expert
  • if applicable, licence to practise medicine, cooperation agreement with medical physics experts, proof of sufficient personnel
