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: 

“The Radiation and Nuclear Safety Authority (STUK), operating under the Ministry of Social Affairs and Health, has been set up to prevent and limit the harmful effects of radiation, to monitor the safety of the use of radiation and nuclear energy, and to conduct research and provide training and information related to them.”

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.
