Editing Fallout shelter (section)

=== Locations ===
Effective public shelters can be the middle floors of some tall buildings or parking structures, or below ground level in most buildings with more than 10 floors. The thickness of the upper floors must form an effective shield, and the windows of the sheltered area must not view fallout-covered ground that is closer than 1.5&nbsp;km (1&nbsp;mi). One of Switzerland's solutions is to use road tunnels passing through the mountains, with some of these shelters being able to protect tens of thousands.<ref name=BBC1>{{cite news|last=Foulkes|first=Imogen|title=Swiss still braced for nuclear war|url=http://news.bbc.co.uk/2/hi/programmes/from_our_own_correspondent/6347519.stm|access-date=August 15, 2012|newspaper=BBC News, Switzerland|date=February 10, 2007}}</ref>

Fallout shelters are not always underground. Above ground buildings with walls and roofs dense enough to afford a meaningful [[Radiation protection#Shielding design|protection factor]] can be used as a fallout shelter.<ref>Monteyne, David.
