ABSTRACT

Small amounts of airborne radionuclides released from the Sosnovy Bor nuclear 
power station were detected on the south coast of Finland on 24th March 1992.
The composition of the radioactive material was similar to that found during the
Chernobyl accident six years ago. However, the radionuclide concentrations were 
now about 1 mBq m3, i.e. five orders of magnitude smaller than the maximum 
concentration detected in Finland during the Chernobyl fallout.

The consequences of the incident in Finland are only of theoretical interest. No 
countermeasures or protective means were needed. However, the studies showed 
that the release contained not only radioactive gases, such as noble gases and iodine,
but also other substances that were most likely dispersed as small particles.
