Professional qualifications granted by STUK

In operations that require a safety licence, the operator must appoint a person responsible for radiation safety (STV) to assist the operator in the implementation of radiation protection. The person responsible for radiation safety, or a radiation safety officer, ensures that radiation protection is arranged and that the radiation practices adhere to regulations.

In activities requiring a safety licence, the operator must also use a radiation safety specialist (STA) to plan, implement and monitor the radiation protection of workers and the population. An STA is not required for radiation activities that do not result in occupational or potential exposure, or expose the population to radiation.

Healthcare and veterinary medicine

Hospital physicists may work as radiation safety specialists without separate approval in the competence area Radiation in healthcare and veterinary medicine.

Industry, research and the use of nuclear energy

You can apply for a qualifications certificate in industrial and research radiation activities or the use of nuclear energy from the Radiation and Nuclear Safety Authority (STUK).

Email the application to the STUK registry: stuk(at), and name the message as “Application for the right to act as the STA”. If possible, send the entire application and its appendices as a single attachment.

To whom and on what terms

You can apply for the right to act as the STA by submitting a form to the STUK registry. Prerequisites for establishing STA eligibility are a suitable master’s degree, specialised radiation protection training and sufficient professional experience in a field suitable for the task.
