Five homes remain in nuclear zone

An emergency planning zone around a former nuclear power station in Caithness has been reduced from three miles to less than one.

The smaller area circling Dounreay has five neighbouring households within its boundary, instead of more than 200.

The zone is covered by detailed plans to deal with the worst-case radiation emergency that can be "reasonably foreseen".

Dounreay said the reduction reflected a lower risk posed by the site.
