On August 8, 2019, a test of a Russian nuclear-powered rocket engine for the “Skyfall” or Burevestnik cruise missile program exploded on its launch platform at the Nynonksa test range above the Arctic Circle on the White Sea. At least five scientists and workers have been killed and dozens injured. Sustained gamma radiation was measured at multiple monitoring stations for 40 minutes to an hour, eighteen miles away in the closed military city of Severodvinsk (pictured by ?????? ???????? for Wikimedia Commons). The radiation is reported to have spiked six to twenty times above normal before documentation was shutdown. As concern grew over the potential radiation exposure to the 500 residents of Nynoksa, the village nearest the explosion, on August 13th the Russian military ordered their evacuation but rescinded it only hours later. Since the accident, the 180,000 residents of Severodvinsk have been seeking and ingesting potassium iodide (KI) to block the uptake of cancer-casuing radioactive iodine to the thyroid gland. Saturating the thyroid with stable iodine is a critical prophylactic for the limited radiation protection it offers the most vulnerable population (infants, young children and pregnant women). According to the American Thyroid Association, KI should always be used as an “essential adjunct” to prompt evacuation or limited sheltering-in-place and restricted ingestion of contaminated food and water.
