Russian news outlet reported that residents of the cities of Severodvinsk and Arkhangelsk have been scrambling to buy iodine from pharmacies, many of which have sold out. Potassium iodide can hinder the collection of radioactive iodine-131 in thyroid glands, which can cause cancer.


According to Reuters, an authority of a port of Arkhangelsk said the explosion led to the closure of a portion of Dvina Bay in the White Sea, so it can no longer be used for shipping.
