Instructions in case of a radiation hazard

These instructions (Instructions in case of a radiation hazard_2021 (pdf)) provide information on actions in case of an emergency occurring at Olkiluoto power plant requiring public protection measures. An emergency of this kind is highly improbable, but still possible.

In case of an imminent radiation hazard, the authorities will issue instructions to the population, for example, on sheltering indoors, taking iodine tablets and evacuation. These measurements are designed to prevent direct health hazards and minimise the impact of radiation.

Pursuant to the Decree of the Finnish Ministry of the Interior (YVL 774/2011) on communication of information in a radiation hazard situation, these instructions for action are distributed to population in the vicinity of the power plant every three years.
