Licensing and notification for research involving ionising radiation
This page is intended for those planning to conduct research involving ionising radiation. It provides information on which types of research activities require a licence or a notification, and how to submit an application or notification.
A licence is required for high activity sealed sources (HASS), particle accelerators and open (unsealed) radioactive sources. If you plan to conduct research using, for example, density gauges, thickness gauges, surface density gauges, moisture meters, eliminators, ionisers, X-ray fluorescence (XRF) instruments or cabinet X-ray systems, you must instead submit a notification.
Anyone applying for a licence or submitting a notification must meet the requirements set out in the Radiation Protection Act (1988:220), the Radiation Protection Ordinance (2018:506) and the Swedish Radiation Safety Authority’s regulations.
Activities requiring a licence
Examples of research activities involving ionising radiation that require a licence:
- Use of high activity sealed sources (HASS) in research applications.
- Use of particle accelerators.
- Use of high activity sealed sources (HASS).
- Use of open (unsealed) radioactive sources.
Under the Radiation Protection Act (2018:396), a licence is required for research involving ionising radiation. The Swedish Radiation Safety Authority normally issues licences to legal entities such as companies or research institutes. The licence holder is responsible for ensuring that all radiation activities comply with the regulations. Licence applications are subject to a fee.
Activities subject to a notification obligation
Examples of technical equipment used in research that are subject to notification:
- X-ray fluorescence (XRF) analysers
- Cabinet X-ray systems
The notification requirement applies in accordance with Chapters 5–7 and 11 of the Swedish Radiation Safety Authority’s Regulations (SSMFS 2018:2) on Activities Subject to Notification.
