Radioactive Fallout

[NorthernRaider]

Dont forget chaps your both looking at absolute worst case scenarios of major direct ground burst nuclear strikes near your homes, but in fact few if any military forces with such capability even use multi megaton ground burst weapons any more, they were only needed when missile and MIRV navigation systems were so innacurate that they had to use HUGE devices in a effort to hit the target.

Modern guidence systems are now so good that most nukes are in the kiloton ranges now AND more importantly they are nearly all AIR burst weapons so fallout is almost nothing, and its Heat, Blast and EMP to deal with.

The prime risk infact in the Uk is just a dity bomb, IE some camel jockey putting radioactive material around an ordinary bomb and setting it off in a city centre.

Or a leak from Chernobyl or Fukushima event is far more likely and well worth having plans for.
