The Radiation and Nuclear Safety Authority (STUK) monitors the radioactivity of food in order to ensure that radiation levels in products are acceptable for human use. Furthermore, the results provide information that is useful for responding to possible radiation hazard situations.
With regard to radiation exposure, the most important food categories are natural produce and household drinking water. Natural produce includes berries, mushrooms, meat and game from forest environment as well as freshwater fish. From the nutritional aspect, farm produce is also an important food category. The transfer of radioactive deposition into food has been the subject of extensive study for decades, and the impact of a possible new deposition on the radioactivity of food can be well assessed.
