Overview

• Sergei Karaganov urged preparing to strike Europe on Russian state television as Vladimir Solovyov floated Oxford and Cambridge as targets, though these are commentator remarks rather than official policy.
• Dr Arnab Basu advises those outside an immediate blast zone to move to the centre of a building or a basement, seal windows and doors, fill containers with water, and remain indoors for two to three days.
• NuclearSecrecy’s NukeMap scenarios show an 800‑kiloton detonation over Cambridge would vaporise the inner zone and produce concentric areas of severe blast, fire, and burn injuries, with outcomes dependent on yield, height, and weather.
• The ICRP says people typically have about 10 minutes to reach adequate shelter, recommending brick or concrete structures and underground garages, while some experts warn parts of the London Underground may not be deep enough in a direct hit.
• Distance‑based safety lists point to relatively remote areas such as Skegness and Foula as better options than major cities, though fallout patterns and winds could still pose risks.
