organisation and management team
The Radiation and Nuclear Safety Authority (STUK) is the authority responsible for supervising radiation and nuclear safety in Finland. STUK’s operations are based on the Act on the Radiation and Nuclear Safety Authority. The first section of the Act defines STUK’s role and status as follows:
In our society, radiation and nuclear energy have been harnessed to contribute to the common good. At STUK, we promote the safe use of radiation and nuclear energy and, together with various actors, ensure that radiation can be utilised safely and that we can live with it safely.
As the global security situation changes and challenges societies, we must understand even better than before how the use of radiation and nuclear energy affects things and what are all the things affected. In our operations, we must take into account both the risks caused and the benefits produced to society, the environment and people in a balanced way.
We do meaningful work that improves safety and invest in a good work community that values everyone’s contribution. We have more than 300 employees. We are experts in many fields, but we are all working together for the same cause – radiation safety.

The Nuclear Reactor Regulation Department ensures that Finnish nuclear power plants are designed and operated in accordance with the relevant regulations and that their use does not cause harmful radiation effects to the health of the plant’s employees or members of the public or damage to the environment or property.
The monitoring of the safety of the use of nuclear energy is a continuous process. Our supervision consists of licences and approvals required under the Nuclear Energy Act, inspection of official documents submitted to us, inspection of the operations of licensees, and inspections of the manufacture, installation and commissioning of structures and equipment.
By supervising nuclear facilities, we ensure that the nuclear facility is designed, constructed and used in accordance with the Nuclear Energy Act and the regulations issued under it and the decisions issued by us. We also supervise the use of other nuclear energy to ensure that operations are safe and meet the requirements of legislation and regulations as well as the obligations laid down in international agreements.
The power company is responsible for the safe operation of the power plant. We set the safety requirements for its use and verify compliance with them with versatile inspection programmes.
The department is headed by Tapani Virolainen. It has slightly over 100 employees.
In the Nuclear Waste Regulation and Safeguards Department, our responsibility for supervision begins with uranium production and ends when the fuel made from uranium is permanently placed in Finnish bedrock. The processes in between include the transport of uranium and uranium fuel, and inspections of nuclear materials, which we carry out on our own or together with the European Commission and the IAEA.
Furthermore, together with customs, we prevent the illegal import of nuclear fuels. We also monitor compliance with the nuclear test ban, low- and intermediate-level nuclear waste, the final disposal project of spent nuclear fuel (PORA project) and plans on how the Finnish nuclear power plants should be dismantled in due course and how this will be funded.
In addition to supervision, our department’s competence is needed in international tasks and expert service projects funded by the Ministry for Foreign Affairs and the European Commission.
The department is headed by Jaakko Leino. It has about 20 employees.
We ensure for our part that the use of radiation is safe in Finland. We have over 3,000 holders of safety licences and thousands of users of non-ionizing radiation under our supervision.
Our experts supervise radiation therapy procedures, the use of radiation in nuclear medicine and the use of X-radiation in health care and veterinary medicine. We also process licence and notification matters falling within our area of responsibility. In addition, we maintain a register of health care safety licences, decisions, approvals and radiation sources.
Our experts in industrial radiation activities and dose control monitor the use of ionising radiation in terms of occupational and public exposure. We also monitor activities in which naturally occurring radioactive materials (NORMs) are used as a source of radiation. Furthermore, we monitor flight operations in terms of occupational exposure. We process applications and notifications falling within our sphere of responsibility, carry out inspections, and maintain and develop the dose register and safety licence register in our area of responsibility.
Our experts in the monitoring of natural radiation monitor radon in workplaces, radioactive substances in construction materials and NORMs. They also develop monitoring processes for these, issue statements related to natural radiation and participate in various projects as experts in the field.
Our experts also ensure that radiating consumer products are safe and that the health hazards of UV radiation are effectively prevented. We also process laser performance permits and monitor the safety of the use of radiation in the beauty care sector, but we do not take any position on the functionality, efficiency or results of such treatments.
The department is headed by Tommi Toivonen. It has about 50 employees.
The Department of Measurements and Environmental Monitoring is tasked with producing radiation-related calibration and measurement services, providing remote and expert support for radiation measurements in the field, and monitoring the radiation safety of the environment nationally and in the areas around nuclear power plants.
In our area of responsibility, we monitor the radiation safety of the environment in Finland and in the areas around nuclear power plants, maintain and develop field and laboratory functions to quickly detect and investigate abnormal radiation situations and, if necessary, provide executive assistance to other authorities in radiation measurements. In addition, we maintain measurement norms for dose quantities, activity and activity concentrations of ionising radiation and provide expert and measurement services. We also coordinate radiation safety research conducted at STUK and domestic and international radiation safety research cooperation for STUK’s part.
The department is headed by Pia Keski-Jaskari. It has about 60 employees.
At department for Expert Services , we coordinate and develop our preparedness activities, communications and public relations as well as our international expert services.
We cooperate extensively with all our departments and our various partners. Our department’s activities are based on the versatile expertise of our organisation: we communicate expert information and views, act as radiation experts in dangerous situations and, in international projects, we also share our expertise outside Finland’s borders.
The department is headed by Karim Peltonen. It has about 20 employees.
The Administration Department is tasked with supporting the work of all STUK employees. We are responsible for such functions as the administrative and financial tasks carried out by STUK and the provision of expert services for international projects. The experts of our department work in document management, procurement, human resources management, management systems, real estate services, legal affairs, information management, financial administration and digitalisation.
The department is headed by Markku Kivioja. It has about 50 employees.
