Säteilyseuranta

Säteilyseuranta, meaning radiation monitoring in Finnish, refers to the systematic measurement and observation of ionizing radiation levels. This practice is crucial for ensuring public safety and environmental protection from potential sources of radiation. In Finland, Säteilyseuranta is a key responsibility of the Radiation and Nuclear Safety Authority (STUK).

The primary goals of Säteilyseuranta include detecting any abnormal increases in radiation, identifying the sources of such increases, and assessing the potential risks to human health and the environment. This monitoring is conducted across various environments, including natural background radiation, workplaces where radioactive materials are used, and areas surrounding nuclear facilities.

Various methods are employed for Säteilyseuranta. These can range from fixed monitoring stations that continuously measure ambient gamma radiation to mobile units used for targeted surveys. Personal dosimeters are also utilized to monitor the radiation exposure of individuals working with or potentially exposed to radiation. Environmental samples, such as air, water, and soil, are regularly collected and analyzed to detect the presence of radioactive substances.

Säteilyseuranta plays a vital role in preparedness for nuclear or radiological emergencies, allowing for rapid assessment of the situation and the implementation of necessary protective measures. The data collected through these monitoring efforts is essential for informed decision-making by authorities and for maintaining public confidence in radiation safety.
