Their source is unknown.
Small concentrations of radioactive substances have been detected in the air in several Finnish cities. This was reported on January 30 by the country's Radiation Safety Service (STUK).
In the period from January 12 to 19, manganese (Mn-54), iron (Fe-59) and cobalt (Co-60) were detected in Rovaniemäe. In Kuopio only cobalt was detected, and in Imatra - manganese, iron, cobalt and niobium (Nb-95).
The STUK explained that such radioactive substances can be formed during the operation of nuclear power plants and released into the air during maintenance. However, the source of these substances remains largely unknown, but in this case it has been confirmed that they do not originate from Finnish nuclear power plants.
The concentrations were very low and not dangerous to people or the environment.
STUK monitors radioactive substances at eight plants in Finland by collecting large volumes of air to measure particles on special filters. Even very low concentrations of radioactive substances can be detected using this method.
