Tiivistelmä
A serious radiation hazard situation is highly unlikely, but we must nevertheless be prepared. A radiation hazard situation requiring protective measures over a large area could be caused by a serious nuclear power plant accident in Finland or in a nearby country, or by the detonation of a nuclear weapon near Finland. A local radiation hazard situation could be caused, for example, by the release of radioactive substances by an explosion or by a serious accident in the intermediate storage of spent nuclear fuel. The effects related to the use or transport of radiation sources are limited to the interior or the immediate vicinity of the site of the incident.
The radiation situation in Finland is being constantly monitored. Finland has a nationwide, automatic radiation monitoring network, which detects all changes in the radiation situation immediately. Domestic nuclear power plants report even minor disturbances to the Radiation and Nuclear Safety Authority (STUK). Neighbouring countries also report disturbances and accidents as soon as possible. Rapid exchange of information enables timely implementation of the required protective measures. STUK’s expert on call receives all radiation- and nuclear safety-related domestic and international notifications and is prepared to take action quickly 24/7 as necessary. The authorities have planned the actions to be taken in a radiation hazard situation and have practiced them regularly.
If the situation requires immediate protection, people are warned with general emergency signals and emergency warnings on TV, radio and in the 112 Suomi mobile application. If you hear the general emergency signal, you must go inside and follow the instructions of the emergency warnings.
Information about the situation and required protective measures are provided through the media and on the websites of the authorities as well as on social media throughout the situation. General guidelines concerning radiation hazard situations are provided in this brochure and on the Rescue Services website (pelastustoimi.fi), the Radiation and Nuclear Safety Authority website (stuk.fi) and YLE teletext pages
867–868.
