Regulation of operations
We are currently updating our For the users of radiation -pages. Up-to-date information can be found on the Finnish and Swedish pages.
The Radiation and Nuclear Safety Authority (STUK) regulates the use of radiation. Radiation is used in health care, industry and research. The use of radiation must be acceptable, planned and safe.
Changes in the use of radiation
If there are changes in the use of radiation by a licensee, they must be reported to the Radiation and Nuclear Safety Authority in writing.
Inspections
The Radiation and Nuclear Safety Authority conducts inspections of places where radiation is used. Inspections help ensure that the use of radiation meets the safety requirements presented in the statutes and meets the licence conditions and regulations.
Implementation procedures
The safety licence system, inspections at the place of use of radiation and the necessary orders, prohibitions and enforcement measures form a system for regulating the safety of the use of radiation which is based on the Radiation Act. The enforcement measures are the strongest method the authority can use to correct discovered deviations.
Veterinary X-ray examinations
The regulation of veterinary X-ray practices emphasises the radiation safety of veterinary personnel.
Dental X-ray examinations
Justification analysis by a dentist is required for dental X-ray examinations.
Transport of radioactive substances
Radioactive substances constitute class 7 in the legislation governing the transportation of dangerous goods. The transport of a radioactive substance is also considered use of radiation under the Radiation Act, but in the Act it has been exempted from a safety licence.
Warning signs
The responsible party must mark radiation appliances, radioactive substances and their usage and storage locations with the appropriate warning signs.
Radiation measurements
Radiation measurement is necessary in many different places and for a variety of reasons. Meters are made subject to different requirements that can be found in Guide ST 1.9.
Activities that expose people to cosmic radiation
Cosmic radiation is particle radiation from the sun or other parts of space. If there is a possibility that the effective dose of aircrews due to cosmic radiation could exceed 1 mSv per year, the responsible party engaged in aviation operations must investigate the extent of cosmic radiation exposure of aircrews.
