International collaboration on radiation safety

International collaboration on radiation safety

STUK participates in international collaboration for the purpose of developing radiation safety

STUK’s employees are members in many international working groups.

International Atomic Energy Agency IAEA

STUK’s representatives participate in the work of IAEA’s Commission on Safety Standards (CSS) that directs the preparation on instructions on radiation safety, and in the work of the committees that deal with the content of the instructions. These are

  • NUSSC, nuclear safety
  • WASSC, waste safety
  • RASSC, radiation safety
  • NSGC, nuclear security
  • TRANSSC, transport safety

World Health Organization WHO

STUK’s representatives are highly sought-after experts for participating in conferences on radiation safety and presenting Finnish good practices to an international audience.  Some good examples of these are the clinical auditing practices for the use of radiation in health care, and the methods for determining population exposure from quantity summaries of medical examinations that expose people to radiation. STUK is also actively engaged in WHO projects on the safety of non-ionizing radiation.

Working Groups of the European Commission

STUK’s representatives participate in the expert groups of the European Commission under the Euratom Treaty.  The expert groups serve as advisory organs for the Commission in matters related to radiation protection.


The goal of HERCA (Heads of the European Radiological Protection Competent Authorities) is to promote a widespread awareness and adoption of good practices on radiation safety and its monitoring in the Member Countries.  STUK has been a member of HERCA since its establishment in 2007.  STUK’s representatives participate in HERCA’s working groups, for example in health care, industry, readiness operations and exposure monitoring.

Nordic collaboration between authorities

The collaboration between Danish, Icelandic, Norwegian, Swedish and Finnish radiation safety authorities goes back a long way.  The Director Generals meet annually to review the results of collaboration groups and to discuss topical matters.  STUK’s representatives participate in the working groups of health care, industry, metrological standards, preparedness and communications.  The working group on non-ionizing radiation regularly arranges thematic workshops.  If necessary, the Nordic authorities issue joint statements on topical matters.

Regulatory control of transport of radioactive substances

The entire Europe follows the same regulations based on IAEA’s requirements on the transport of radioactive substances (for example the ADR and RID treaties). STUK collaborates in the organization for European authorities in fields like common instructions and harmonization of requirements.

European research collaboration

Research on radiation safety is a fairly narrow, but multidisciplinary field in the European countries. To increase the critical mass, several European countries decided a few years ago to combine their strength and establish a research consortium.  STUK’s representatives participate in these networks of experts (MELODI, NERIS, EURADOS) to influence the development of research.



International metrological activities for ionising radiation

STUK’s representatives participate in the operation of EURAMET, an association that is concerned with the reliability and quality of radiation measurements.  The EURAMET network maintains the metrological standards for the most important dose quantities under the Mutual Recognition Agreement (MRA) of the International Committee for Weights and Measures (CIPM) in all Member Countries. In addition, the EURAMET network participates in European research programs on radiation measurements. STUK has also been a long-time member in the network of calibration laboratories maintained by IAEA and WHO. Under this collaboration scheme, STUK participates in working groups on guidelines on radiation measurements, for example.
