Monitoring of Cs-137 and Sr-90 in river water in Finland

Monitoring of Cs-137 and Sr-90 in river water in Finland

 

AbstractMonthly observations of 137Cs and 90Sr in river water samples from the 5 large rivers in Finland since 1965 have been recorded by STUK. Some of the rivers are located in areas that received significant deposition from the Chernobyl accident.

Sample number>1000
QualityData have been collected as a part of STUK’s environmental monitoring program since 1965. Since 1999, radioactivity determinations have been carried out using an accredited method with regular quality control through intercomparisons, calibrations and blank samples. Prior to 1999, in-house quality evaluation took place with similar quality assessments. Locations are currently recorded by name or name of the river where the sample has been collected.
