The Radiation and Nuclear Safety Authority of Finland published its first press release on afternoon 28 April 1986 about elevated radioactive radiation observed in Finland, "probably from some reactor accident". On that time the Soviet Union hadn´t yet admitted the accident.
The level of radioactive radiation in Finland was not at alarming level even in the beginning, so no acute civil defense actions was needed in Finland. Anyhow, the fallout reached also our soil in some extend and as a security measure there were introduced some temporary reductions for cattle´s crazing (outside). Finns were also recommended in longer period not to eat too much mushrooms, berries or other natural products from the areas in Finland which received the most amounts of small fallout. The monitoring of the radiation related to Chernobyl catastrophe has continued in Finland until nowadays and will continue.
When the accident happened, it was more than 100 Finns that were residing in Kyiv area. The Finnish authorities, as many other western countries, decided to repatriate their citizens. The evacuation flight with more than 70 Finns on board was able to leave Kyiv on 1 May 1986 and arrived to Helsinki on the evening of the same day.
The Chernobyl catastrophe also affected the nuclear policy of Finland and plans for a new nuclear reactor was cancelled for two decades.
