No radioactive substances carried to Finland following the Russian missile accident
The Radiation and Nuclear Safety Authority has completed the preliminary analysis of the air particle samples collected in Kuopio, Imatra, Kotka and Helsinki during the last couple of days. The method used by STUK would detect even the lowest concentrations of radioactive substances. The samples showed no deficiencies from normal values. The samples collected at the remaining four outdoor air radioactive particle sampling stations in Finland will be analysed following the normal practice within the next couple of days.
According to the news, radioactive substances were released into the environment as a result of a missile accident that took place in Russia, near the city of Severodvinsk on 8 August. There have been no air currents from the accident area to Finland. Furthermore, it was reported that the radiation dose rate increased to two microsieverts per hour near the incident location for a short period of time following the accident. Such a dose rate is clearly higher than normal but causes no danger to people in the area. It can be compared, for example, to the dose rate of radiation caused by cosmic radiation inside an airplane flying at ten kilometres, five microsieverts per hour.
STUK has no detailed information about the accident. The accident took place during the testing of weapons systems, and the Russian radiation and nuclear safety authority could therefore not release any information concerning the incident to STUK.
