STUK's finances and personnel in 2022

STUK's operations are net-budgeted, which means that part of the expenditure is covered by the agency's own supervisory and service revenue.


In 2022, STUK’s operating expenses were approximately EUR 40 million. Personnel expenses in 2022 amounted to EUR 25 million, approximately 62% of total expenses. STUK's acquisition costs (e.g. rents, services) totalled approximately EUR 15 million.

Of the funding of STUK's operations, 16.9 million came from the taxpayers from the government’s budget appropriation. Nearly one half (20.7 million) was collected by STUK as regulatory charges from the organizations being monitored. Of the regulatory charges, the greatest portion by far (nearly 20 million) came from the safety monitoring of the use of nuclear energy, and the remainder from the monitoring of radiation practices.

Income from service activities was nearly 2.2 million, up by +9% on the previous year. The most significant reason for the increase in revenue from service activities is the increase in commercial project activities in STUK's international expert services. In 2022, STUK's revenue from standard services – such as radon measurement services, radioactivity certificates, analyses of environmental samples and other measurement services – totalled approximately EUR 1.3 million.
