Distribution of iodine tablets: a precautionary measure
In Switzerland, everyone living within 50 km of a active Swiss nuclear power plant is provided with a pack of iodine tablets (potassium iodide 65 SERB tablets) by the federal government free of charge. This is a precautionary measure. In the event of a serious incident at a nuclear power plant, these tablets prevent radioactive iodine from being absorbed by the thyroid gland and leading to thyroid cancer. In regions outside of this 50 km radius, the cantons store enough iodine tablets to supply the population in good time should the need arise.
Important: The tablets are intended for use in an emergency and must not be taken unless directed by the authorities. If an incident occurs, the population will be alerted and informed accordingly.
