maybe the tail end of Cornwall too.
That's assuming the debate about "nuclear winter" vs "nuclear autumn" turns out to be like Ferguson's covid modeling on the nuclear winter side, because if not we're mostly all going to starve in the event of a massive exchange of weapons and what remains of humanity could easily be sent back several centuries in terms of development.
With the likes of Culdrose probably not a great bet.
Most nuclear winter studies have serious flaws - such as assuming all bombs in an attack hit dense urban environments when in reality lots would be aimed at military and infrastructure locations which are often sparser.
